Troubleshooting Heat Pumps Problems & Solutions
In the USA, usually when the 4-way valve is ON, the system is operating in the cooling mode. When it is OFF, it is operating in heating mode. In some other countries, when the 4-way valve is ON, the system is operating in the heating mode and vice-versa.
Does Not Heat or Cool Correctly
Charging of a heat pump in the cooling mode isn’t much of an issue unless you are experiencing low ambient or low load conditions. Charging a heat pump in the heating mode can be a bit more complicated. To my knowledge if a charge issue is suspected in the heating mode that charge is to be recovered and weighed in per the nameplate data on the equipment according to the manufacturers. Some manufacturers will provide charts to quick check a heating charge but they are not designed to charge accurately in the heating mode.

Troubleshooting Problems With Your Heat Pump
A heat pump that doesn’t turn on is a fairly common and easily remedied problem. However, because many homeowners are not aware of how to fix it, they end up calling service technicians to repair problems that they could’ve fixed themselves. For example, some of the issues that can be easily repaired by homeowners include:
Steve, thank you for getting back with me. I did your test and yes the fan is hot so t looks like I need a new motor, however, in the process of testing the fan motor I now seem to have another problem. No cool air and the compressor does not come on. Do you think I destroyed the compressor trying to test the fan motor. The motor was very hot. Should I try your Super Booster to see if it would start? And if so and it works then comes the problem of where would I get a new fan motor since you said don’t carry my brand? Any suggestions would be very helpful.
