I have a 3003 Master station that had been hit by loightning at least 4 times. It was repaired or replaced each time. I have so much money tied up in this unit. It still works as a doorbell but can barely hear the radio at the master staion and to turn it up you get a screeching noise. Can anyone send me the schematics and or which part to replace. I have my house up for sale and seriously need to get it repaired 1 more time as cheaply as possible. Thanks in advance

How would I go about getting a schematic for a NuTone "Scovill" IMA-203? When I moved into my home I was told the system was inoperable. I have found it is not fully operable, and I believe it can be. Please assist. Thanks

Could you email me directions on how to change the time on my NuTone intercom? The model number is 3003. Any help would be appreciated. Thank you.

Hello, I have a system (approx. early 80's)which the chime quit working. The insruction sheet that I found says it is a: NUTONE 3-Station Door - Answering Intercom Model : IK-25 What is confusing is, when I pulled the outside housing, it says Nutone Scovill (it is brown with Goldtone area where lighted door bell pushbutton is and on the inside close to the bell button it has a raised "Model" IS 67 showing. I need the replacement speaker and possibly the 2 blue capacitors that appear to be tied in series. I pulled the button for chime & the bulb and when I jump the two wires, I still get nothing as far as the chime working. Any ideas? The speaker for outside says B-36076 and 16 ohm 1 W Korea. This is on the speaker magnet. Guess the first question would be.. the burnt out or lack of bulb should not affect the chime? I have power at the transformer, but none at the 2 wires connecting to the bell push button.Any input would be appreciated before I change out the existing system. Thank you.. Dennis

I am wondering if you could help me find a screen for a rather old range hood it's a Nutone Scovill, on the right side there marked Solid State - Selectamatic I can find no readable part number, but the screen I need to replace is rather long, and clips on each side. I don't have it in front of me, but it actually bends up and attaches at each side, and the middle part is at least 12 x 10". It might be between 20-24" in length, so it is much bigger than your normal range hood screen. If you can offer me any help, I would appreciate it. Thanks.

Looking for several things - a operators manual, an outdoor speaker and what would cause the speakers throughout the house to click and have static every once in a while. We have an NuTone IM 4006 system

We just purchased a home with a NuTone Intercom System the IM4006. Every now and then we hear clicking throughout the house via the speakers and sometimes the release button after speaking does not release so that we can go back to the radio. Therefore I'm looking for any help here? I'm also looking for a manual on this particular unit. Any suggestions? And finally, I'm looking for an outside speaker for our unit - have the wires but the speaker is missing. Thanks for you help in advance!

Just moved, house has a 3003 series intercom, not working properly. Do you service, in Toronto Canada. OR is replacement better..? Andrew
