NuTone started making music intercom systems back in the 1950's, and for the past 55 years homeowners have had a hard time finding someone to service and repair their systems. As one of my favorite electrical contractors would say "those NuTone systems are finicky"!
Having spent the past 30 years servicing and repairing NuTone Intercom systems, there is very little that I haven't seen (although I do get surprised now and then).
The way I approach intercom problems is fairly simple. Every model that NuTone has ever made has a list, and on that list are the 10 most common problems with each model. What the 10 problems are will be different for each model and be different as models age.
For instance, 10 common problems with an IMA4006 when it was new will be different than the 10 common problems when it is 25 years old.
One thing I tell my customers is that when a system has a problem that isn't on the 10 most common list, the problem is usually something simple or something expensive. This may sound odd, but it is most often true.
In this section I will be outlining the ten common problems with each model of NuTone Intercom systems.
There will be some history about NuTone intercoms, which helps put things into a context and this makes understanding the problems and solutions easier.
You can also ask questions regarding problems with your system by using the email link on this site.
I have begun adding downloadable NuTone Service manuals on the Service and Repair Manual page. These are the actual factory manuals which I learned from and each model can be repaired with.
There's no reason to live with a broken intercom system, lets find out what's wrong and fix it.
