Abnormal Replace the compressor. 8.1.7 Only outdoor fan motor does not run. Check the fan rotation Check if foreign matter is in the fan cover.
- Page 30 C. Check the switch transformer for sounding. If the transformer sounds, remove the load on the power supplies of 30V DC and 12V DG. If still without 30V DC output after removal, then the switch power is defective. If with 30V DC output, the load is short – circuited but the switch power is good. Then check the secondary load circuit.
