If the fan in your Carrier Heat Pump is running but you're not getting any cooling or heating, it could be due to incorrect temperature settings. Make sure to set the temperature correctly. Also, there may be a time delay in compressor operation, so wait at least three minutes for the compressor to come back on.
What to do if my Carrier 38VMH-1P Heat Pump has no cooling effect?
If your Carrier Heat Pump isn't cooling, the heat exchanger of the outdoor or indoor unit might be dirty or blocked. Clean the heat exchanger and remove any obstructions. Also, the air filter of the indoor unit could be dirty; clean or replace it. Check for leaks and refrigerant charge, and ensure that the outdoor temperature is within normal limits.
What to do if my Carrier 38VMH-1P Heat Pump unit will not start?
If your Carrier Heat Pump unit won't start, there might be a few reasons. First, check for a power supply failure and recover the power supply. Then, ensure the power switch is turned on. Finally, inspect the fuse and replace it if it's burned out.
Why does my Carrier 38VMH-1P start and stop frequently?
If your Carrier Heat Pump starts and stops frequently, it could be due to an incorrect refrigerant charge; check for leaks and refrigerant charge. Air or other gas in the refrigerant circuit can also cause this issue; vacuum and recharge the refrigerant. Also, improper voltage could be the cause; the voltage measured between L1 and L2 should be 187 to 253 volts.
