Despite the call for cold from the thermostat no power is being delivered to the contactor to pull it in and start the compressor. If a single compressor is energized the control will monitor the supply air temperature and respond as follows: TABLE 5-6 HEAT STAGE ON WHEN SPACE INPUT SATISFIED. It does not seem to be blowing very well. 0000013337 00000 n A bad reversing valve on an air conditioner or heat pump can usually be found by checking the temperatures on the four refrigerant lines entering and leaving the valve. when I turn on my ac instead of cooling the heat comes on. Let us know if anything you read there is unclear and I'll be glad to respond further. Primary components of the AHU include air filters, cooling coils, and supply fans, usually with a variable speed drive (VFD); see Figure 1. 0000005609 00000 n The sound comes once and then it's gone till the next cooling cycle (when the compressor switches on and switches off again). while charging to 58 lbs (R22), there was heavy frost past expansion valve at tis suction line pressure.

In VAV systems, the supply air temperature, as well as the supply air volume, are continuous functions of zone air temperature. Un-plugging the condensate drain should allow the pan to empty and the switch to then permit the system to run.
