Thank you for the reply. Im sorry if I was not clear. I understand the breaker and compressor, I am an RV tech by trade .Yes 8 amp running is normal with an initial kick at startup of approximately 17 amps for about 1.5 sec. These are normal Amp loads. My reference to the 8 amps was simply to let everyone know that this component ( triac ? ) has a normal load of 8 amps that goes threw it and no more than 20 amps as the breaker was a 20 amp. Sorry for the lack of clarity on my part.
Yes the start and run capacitors are good (was the first parts I replaced out of habit for AC compressor no start ) and the run cap for the fan is good as well. This little thing (part) is in the control box for the unit, located in the ceiling assembly inside the coach. The compressor has a constant 120 volt to it and this interrupts the neutral when the main switch is in the off position or the thermostat no longer calls for cooling. My diagnosis for the fault of the part was when the unit calls for cooling, i get 5.1 volt AC on the gate( signal) , I have 120 volt to this component from the compressor, but nothing coming out to complete the circuit. If I bypass the component with a jumper wire, went from the post with the neutral line to the compressor to the post that goes to neutral on the board, the compressor kicks on as it should and pulls normal amp loads. my question is I cant find / or know of a replacement part for this, not even sure what the part is called. I was thinking it was a triac but everything I have been told was a triac uses DC voltage for the gate not AC.
it is on a Coleman Delta T RV AC. Top unit mod # 6768-708 SN 078501944 Ceiling Assy mod # 6769A714 per Coleman unit and parts have been obsolete for almost 20 years
