I have a york rooftop that uses the tdr sequencer to control the fan during heat. i replaced one back in november then it failed again in January
(ijust figured bad one at that point) but now it failed again.
the coil voltage is good the amps going through the contacts are like .05 amps.
It does not matter but the I.D. blower amps are even good . ( though blower amps should be irrelevent)The system if it fails will work in fan on but that is controlled differently (I know). is it possible that the blower contactor coil could be causing this premature failure?? like I said earlier it last a little over a month. thanks in advance for the info
