Dometic w/hp installed,has 115ac @12dc thermostatworks sends signal but won't fire

Answers :

Hi! there, as you mention since source was 115 voltwas initialized and thermostat detected was functioning but heater won't fire, check if there's incoming source on your heating element using multitester on voltmeter set up,if there's source 115 volt,check your heating element resistance be sure to switch off your ac before checking resistance of your heater (your tester may damage upon testing resistance when ac source was on takenote),set your tester to ohmmeter R10 test rod at both end on terminal take reading if no deflection,you have busted heating element,replaced heating element,If there's relay holding supply on heating element on circcuit board try to check it out.if source 115 volt is acquired,also check the resistance coil of relay,iif defective replaced one...have a nice they.

When I switch the T-stat to (fan on) the blower won't come on unless I move the Fan limit up close to the 100 degree mark and then I move that limit back down close to 130-135 degree and after approx. 10 seconds blower shuts off. I'm not sure where that fan limit is supposed to be set at, it was originally set around 130-135. It's a 2 wire limit and the range is 100-140. I know the stat is sending signal, I get 24v on green term. at fan center relay. Thanks, Dave

I have a Drayton Digistat RF1 with SCR thermostat for my central heating which is about three years old now. It has worked well up to now, but has developed a problem. The red continuous light (alarm) on the SCR keeps appearing.

Hello all~ I have a Carrier WeatherMaker 8000 & it is turning on by itself even though the thermostat is NOT sending the turn-on signal. When this happens, the flame does NOT come on nor does the main fan come on... but instead just the pre-stage fan blower. The duration is 5-10 seconds & the frequency varies from 3-20 times/hour. Also, there are NOT any error codes flashing. Any help would be greatly appreciated! Thanks~ Joey
