Sorry for taking so long, the answer is yes. Voltage is good to the unit
Sorry, but was out of town [Law enforcement business] here's the thing, ! believe that even if the refrigerant was low, the fan would work but the air would be warm. The compressor and fan need 220-244vac to run but the contactor remains open. Nothing is coming on. All you hear is a clicking sound, no humming. The circut board has been replaced and now the double pole contactor has been replaced, same result I have 244vac coming in but the contacts are not closing. When I remove the small panel cover off the DP30242 contactor and manually push down the relays ...it works. Its missing the input power to close contacts I guess.
Okay, this will take a minute. airhandler is in unfinished attic.
Ok I will be here. Russ
