Came home yesterday and no air. Went to the unit outside to reset the breakers since we had a brief storm Friday AM. Still nothing. Went back out and looked inside at compressor area... was frozen, so I turned the power off at the box and let it defrost.
After a good hour + went and applied power... came inside - no power to my digital therm - shucks! Took it off wall - did not mark each wire since I did not know it would be too big a deal since they all colored.
Went this AM to HD and got a Honeywell RTH3100C digital thermo for heat pumps. Started looking at the rewiring diag and thought I should check my unit to make sure all the wiring color matched up... My unit is an older Carrier 38YRA024300 outside with a matching unknown model number split coil-pack and aux electric heater with blower unit under the house. Just did not feel like crawling under the house to check it at the moment.
Found my wiring diag at the Carrier site. C Y O W2 R. C=Blk Y=Yellow O=Orange W2=White R=Red. Fine... except the original contractor used C=White and W2=Blue.
So, following those colors - I wired the Thermo inside replacing the colors according to the colors as wired at the unit. W2 got the blue control wire and white was used where the C=common wire went as per Honeywell's instructions.
Applied my power... setup my thermo for proper Aux heat = electric and the compressor and outside fin cooling fans operate fine... kicks on and starts pumping - but on the inside... I have no air blowing from the under-house coil-pack/blower unit.
Kept doing some reading and things say that the green wire usually controls the blower - it is hooked to the G on the thermo - even tho there was no G wire leaving the outside unit. Both G and Blk are left unused. Not sure the wiring route as the control wires go under the house... do some go to the coil-pack/air handler and then into the wall? Dunno... but I got no blower action.
Could it be that I have something miswired on the thermo... or maybe the air handling blower has bit the dust after 12+ years?
Any help will be grateful!!!
