NuTone has Discontinued Entry Door Station Speaker Cones

We found out 2 months ago that NuTone has discontinued replacement 3-1/2" Entry Door Station Speaker Cones and there are none left in the Parts Department inventory to order.

This was a surprise to us and everyone else, there was no warning that these speaker cones were going to become obsolete.

Due to the high demand for this Speaker Cone, which is used in almost every Model of NuTone Intercom System made since 1974, this creates a problem for the owners of these systems.

In response to this problem, we have decided to work with a Speaker Cone Manufacturer to have exact replacement speakers cones manufactured.

Here's a Video about this situation:

I will be posting updates on this project as it moves forward - Chris



Something New to Report. . . 

I often have customers contact me to see if we are still repairing NuTone Intercom Systems  (Yes - Yes we are)

This comes up because there isn't often much new information to post on this Web Site.  

The descriptions and details about the problems with most older NuTone Intercoms don't change that much at this point.  The problems with a model like the NuTone IM3003 are well documented and the work to rebuild the IM3003 hasn't changed that much over the last 5 years. This is true for many models

Some models like the NuTone IM5006 or the IM5000 have had an increase in the amount of work that should be done when rebuilding a Master Station, however the additional work is incremental and not that interesting to most people (other than me)

I am also concerned that this Web Site is already very big - which makes it difficult for visitors to find the information they're looking for. 

Of course there's also our YouTube Channel - which now has over 200+ Videos.  It's that old saying "A picture is worth a thousand words" 

Well, today there is something new and worthy to report - The beginning of a new chapter for the reapir of the NuTone NM Series of Radio Intercoms.  I am calling it our "NM Series Repair Initiative"

Here's a link to my newest post on about the NuTone NM Series of Intercoms (applies to M&S Systems DMC Series as well)

Here's a link to our YouTube Play List about the NuTone NM Series 

Here's a link to our on-line "Repair Request Form" - If you have a NuTone NM100, NM200 or a M&S Systems (Music and Sound) DMC1 or DMC3-4.  You can fill out the Repair Request Form and I'll contact you directly to discuss the problems with your system and its repair - Chris 


Adjusting your Chime Module Volume - First get the Basic system Adjustments Correct

The single most common problem that customers have with their NuTone Intercom Systems is that they can't hear the Door Chime throughout their home well enough.

While this can be a fairly serious problem with an aging Master Station, it is very often just that the Intercom system is out of adjustment, which compromises how well the Door Chime is heard.

Since NuTone has made Intercom Systems since 1957 and there are dozens and dozens of different models, it's not practical for me to try and describe how to set the adjustments on a Model by Model basis.  It would also be very time consuming to make a YouTube Video for each model.

In many cases the reason that you cannot hear your Door Chime as loudly as you have in the past, is because over time the volume controls on the remote stations have been slowly turned down further than is correct.  When you lower the volume control on a remote station, you are not only lowering the music volume, you are also lowering the Door Chime volume.  

Contrary to to what most people would think to be normal, the volume controls on all of the remote stations should start on the highest setting (turned all the way up).  Whenever I have done demonstrations for customers with a new installation and I tell them to leave the volume controls set to maximum, they give me this funny look - like I'm crazy.  For some reason people are uncomfortable with having anything set at full.

What you may find is that when you turn your volume controls back up (to full) the music volume and possibly the Intercom Volume will be too loud.  This is when you go to your Master Station and readjust the System Adjustment for the Music and Intercom.

Since there are many different NuTone Models, I can't tell you how all of these adjustments will be labeled on your particular model, however for the most part (especially on models made since 1974) you will have an "Intercom Volume" and "System Volume" adjustment.

While NuTone calls these adjustments "Volume Controls", they aren't.  They are actually "Gain Controls".  

Gain Controls adjust the amount of signal that is feed into the Amplifier of the system.

Amplifiers are a fairly easy device to understand.  All Amplifiers are designed to be able to produce a certain amount of power (watts).  So, the questions is, how does the amplifier know how much power to make?

The answer is actually easy - the more signal that is fed into the amplifier, the more power it makes.

As an example, if your amplifier is capable of making 10 times the power of the signal that is fed into it - and you feed in a signal of 1 - the amplifier will make a power level of 10 - if you feed in a signal of 5 - the amplifier will make a power level of 50.

Now back to adjusting your system:

With all of the Volume Controls set to maximum, including the controls on your Master Station, first set the "System Volume" or "Volume to all Speaker" or "Radio Volume" to a level that gives you a comfortable  Day-to-day listening level.  There is no absolute setting for this adjustment - it's simply whatever your comfortable listening level is.

Now, with the help of someone else, try the Intercom part of your System - talking back and forth.  If the conversation is too loud - turn the "Intercom Volume" on the Master Station down to a more comfortable level.  If the communication is too low - turn the Intercom Volume up.

The by-product of setting your system up this way is that now, your amplifier in the Master Station is making just enough power to operate your system at the levels that you need in your home, without making extra power (or working too hard).  The clarity of the music and Intercom conversation should be much higher and making small adjustments (like 5%) to the volume controls in individual rooms will make a noticeable difference in the music level in that room without compromising the Intercom or Door Chime volumes.

After setting up your System this way, you may actually find now that your Door Chime is way too loud, why is this?

Chime Modules were always an optional extra with every NuTone Intercom system.  When the Installer was trimming out your Intercom System, he would have added the Chime Module to your Master Station.  Chime Modules were never preset to any particular volume level, it was the installer's job to set it to a comfortable level after the installation was completed - this often didn't happen or the installer didn't understand how to setup the new system correctly.

If you find that you Door Chime is now too loud, don't worry - there's an adjustment for that. 

Adjusting the Chime Module is easy, however it does require opening up the Master Station - locating the Chime Module and making the adjustment.

To help you with this - you can go to our YouTube Channel - find the Playlist for your NuTone Intercom Model - watch the Video that shows how to open up your Master Station - and take note of the part of the Video that tells you where the Chime Module is located inside your Master Station.

Once you found your Chime Module, watch this Video

This Video covers all of the different NuTone Chime Modules and their Volume Adjustments

What are NuTone MPP Warranty Products?

The NuTone MPP Products Warranty Program started in 1986 - MPP stands for Maximum Performance Product.

The essence of the MPP Warranty Program was that NuTone products that were part of the MPP Program would be covered for Parts, Labor and In-Home Service, to the original purchaser of the product for as long as they lived in the home.

Originally NuTone's intention was to include only parts into the MPP Warranty, but due to a mistake in how the warranty was written, it also included labor and in-home service.  This mistake was not noticed until the beginning of 1987, at the annual NuTone Sales Meeting in Cincinnati.

The annual Sales Meeting was a gathering of all NuTone Sales Reps from around the country.  By the time of the meeting, the MPP Program had been in effect for almost one year and it had become a great sales tool for both the NuTone Sales Reps and NuTone Dealers.

Consumers loved the idea of buying products that would be covered for as long as they lived in their homes.  NuTone wanted to trim back the warranty to its original concept, but the outcry from the Sales Force was loud and clear, and the MPP Warranty was left as was.

The majority of MPP products were in the higher level product models, entry level models and builders models were typically not covered by the MPP Warranty.

By the late 1980's through the mid 1990's the was a building boom going on and NuTone products were the favorite of customer home builders, home remodelers, and home owners alike.  I can tell you that it was a great time to be not only a NuTone Dealer, but a NuTone Service Center as well.

It was not uncommon to perform 10-15 in-warranty service calls per week.  NuTone Service Centers are paid a flat rate on a per call basis.  If a Service Center was well organized and if they could complete each call in one trip, there was money to make.

In the early 1990's NuTone had a change in leadership and its new president was on a cost-reduction mission.  From a Service Center's point of view, the quality of products was slipping and the number of MPP Warranty calls was on the rise.  It was said the at the peak of the MPP Warranty program, NuTone was spending somewhere around 5 million dollars a year on warranty service.

With the increase in warranty calls, there was also an increase in the number of false in-warranty claims made by both homeowners and less than honest Service Centers.  One of the requirements of the MPP Program was homeowners had to provide Proof of Purchase to the Service Center to validate the warranty claim.  To combat the number of false claims, NuTone began to require that copies of the proof of purchase to be sent in with the billing from the Service Call.  There were also a number of Service Centers that were dismissed due to false claims.

There were limitations in the MPP Warranty. It did not cover cosmetic issues like discolored fan grills or Intercom Door Stations that weathered from being outside.  The original MPP Warranty  specifically addressed failures "due to manufacturing defects" which implied that normal wear-and-tear would not be covered.  In most cases it was the Service Center's job to make the determination, as we were the gate keeper of the MPP Warranty.

By 1994 products that had been originally covered by the MPP Warranty were starting to be replaced with newer products.  These new products were covered by a new warranty program, the PPP Warranty.  This was a much more limited warranty; basically it was five years for parts and two years in home service. 

By 2000 the PPP Warranty was eliminated and replaced by a Two year warranty, which covered parts and in-home service.

Around 2010 a decision was made by the management of Broan-NuTone LLC that ended the MPP Warranty Program once and for all.  Service Centers were told that no claims for MPP Warranty repairs would be paid any longer.  This decision was based on the wording in the five different MPP Warranty statements that were included with NuTone products over the years.  The part of the warranty statement that implied or stated that normal "wear-and-tear" was not covered was enough justification to end the program.

Since the oldest MPP Products were then 24 years old and the newest were 12 years old, how could any problems be from a manufacturing defect?  While this is a reasonable concept, the implementation was handled very poorly.  Many calls for MPP service ended up with the customer stating loud and clear "I'll never buy another NuTone product again" then the phone would click as they hung up. 

By 2010, the number of MPP requests were so small and the majority of them were from people that had used the MPP warranty before, and most of them revolved around Intercom equipment. The cost of the warranty was probably much smaller then the cost to the company's reputation by discontinuing the program.


Visit Our New YouTube Video Index Page

I started making YouTube Videos in January 2015 and to date I have 114 different Videos that cover a wide range of topics and problems with NuTone Intercom Systems.

My self imposed pace bacj in 2015 was at least 1 Video per week.  I've been able to exceed that by just a little and I have many more ideas for future Videos.

Cindy has worked hard and put together a new Page on this site to Index all of our Videos.  The Videos are arranged into groups that match our YouTube Video Play lists.

Here's a link to our new Video Index Page - give it a look and see if you can find a Video that will help you with the problem with your NuTone Intercom System
