paauto Posted January 30, 2014 Posted January 30, 2014 I have two ToggleLinc Relays in a bathroom that are controller/responders to "Bathroom Fan" scene. One of the ToggleLincs is connected to the load. They are each on different circuits (not sure if on different legs). Intermittently the fan fails to respond to the ToggleLincs. For example, last night I turned on the non-load ToggleLinc and the Load ToggleLinc turned on, but the fan did not. I then tried the load ToggleLinc and no luck either. I cycled the breakers off/on for both circuits and everything then worked fine. I checked the log and it indicates that both ToggleLincs were switched on, even though the fan did not come on. Thoughts?
LeeG Posted January 30, 2014 Posted January 30, 2014 Loose wire on the load control ToggleLinc, failure of the relay, failure of the fan motor to spin. If the ToggleLinc indicates it is On but the load is not controlled the ToggleLinc hardware, wiring or the load itself has a problem.
LeeG Posted January 30, 2014 Posted January 30, 2014 Exhaust fan motors are not very powerful. I have had to replace fan motors that fail to start using standard switches.
paauto Posted February 20, 2014 Author Posted February 20, 2014 I did some research and via the Insteon Forum it appears I need R-C Snubbers to ameliorate a voltage spike that occurs when an electric motor is turned off (something to do with Faraday's Law, but I'm a finance guy). Anyway, I ordered the things, which appareantly wire between the line and neutral in parallel at the fan and that should fix things. I'll post after I put them in.
paauto Posted February 27, 2014 Author Posted February 27, 2014 I added the RC Snubbers on Monday and since then no more problems with the fans.
