HVAC Emergency service. The Infamous Goodman Blower Relay

An emergency visit for one of my best customers. It turns out that the problem is one of my old friends, the Goodman stack blower relay.

What about the amperage draw accross this relay? If the heater draws 24 amps, is that too much for this relay?

[talyn875]

@ducky69918 the relay actually only controls the blower motor. The heat strip amperage passes through the sequencers. The blower motor is typically less than five amps, which this relay can easily handle. If the heat strips malfunction then they send voltage to this relay to power the blower.

@ducky69918 the relay typically is for less than 10 amps, 25 amps inrush current.

any chance you could help me lol... mine will run fine aslong as the contacter is pushed in but it wont kick the contacter on its own ... i put a new contacter and copasiter on the unit.. do you think its the time delay relay or transformer on the inside unit and how would i test? any suggestions would be awesome thanks.

@dandjscrewover Maybe if I get a chance I will make a video of my contactor tomoorrow and you can see.

youre such a good tech

[talyn875]

@dandjscrewover I'll try. The fact the contactor will not make could be many things. If you have a low or high pressure switch in the low voltage circuit it may have the signal to the contactor shut off. The same can be said for any float controls on the drain pans on the indoor unit. You need to test for a signal to the contactor to start with. There must be a 24 volt signal to the contactor. The low voltage is typically on either side. Test the yellow and blue common wire for 24 volts.
