Nutone 3003 intercom volume button

Nutone 3003 intercom master and program volume buttons don't seem to work; can hear that radio is on, but can't turn up high enough to hear. And system "crackles" even when turned off. Any ideas for a fix?

It sounds like your IM3003 has a failed power supply (not the transformer) You can verify this by turn the "radio power" button to on, then set the selector switch to FM. If the numbers on the display continually change (looks like it's counting) you have a failed power supply and it will need to be rebuilt.

You could also have wiring or remote speaker issues, cause the system to be muted.
