Furnace: Carrier 58MVB120-20 H/P: 25HNA660A0030030
The 3Amp fuse on the 58MVB control board opens almost each time the H/P kicks in. The units are place about 70 feet apart. The furnace operates fine until the temp rises above 32f and H/P low voltage side over draw on the 24vac from the 58MVB control board and opens the fuse.
Which component would you be suspicious of overloading the 24vac power supply on the H/P?
Greatly appreciate your input!
