Air Handler Fan Relay
April 5, 2011
I have a 3 ton air handler in my attic. The fan relay chatters and the motor inside the air handler turns very slowly, and at the same time the fan relay beings to melt.
I have replaced the capacitor and replaced the relay. The relay does the same thing chatters and melts. I have disconnected all the wires going into the relay except the 24 volts to the relay coil.
That's when it still chatters. The N/O side is what melts away. I checked the l.v. transformer and it's putting out 25 volts. the coil is 24v. the n.o. & n.c. is 20/10amp -277v
I give up please help
p.s our central ac unit is 5 years old
