Troubleshooting a carrier air handler heat pump system . Outdoor unit is a goodman. No voltage between common and red outside as well as inside air handler Standing refrigerant pressure reading 75psi R-22. Control board keep blowing . Indoor blower runs as well as electric strip heat. Why do the fuses keep blowing and the outdoor unit not starting. Is this a sighn of a bad control board. No wires are grounded that could blow the fuse I checked thourghly. Ihave also unhooked all the wires from the outdoor unit to the indoor unit as well as the t-stat wires. Replaced the 5amp fuse and check my voltage on the low side of transformer but get no reading between between red and common off the board itself
