My furnace is a Goodman GSU060-3
I had a local HVAC company out March 6th and they told me I needed a new gas valve ($500 installed) because mine had an intermittent short. On March 10th, I reset the breaker & gave the valve a light whack with a piece of wood and the furnace has worked fine until today. I tried the wood again 5 or 6 times this morning but no luck. I can see at least one igniter glowing but don’t get ignition. We had to reset the circuit breaker to the furnace each time and I tried it several times with the gas flow Knob on and off since I wasn’t sure which position was on. Now the breaker won’t stay in the on position, it defaults to a tripped position. I unplugged the molex type connector to the gas valve and the breaker still wouldn’t reset. I found a replacement valve for about $115 that I can get here by tomorrow if I order soon but it doesn’t look exactly or even very similar to mine. Should that be a concern? It isn’t returnable after I install and try it.
I have a Multimeter and I can do a continuity test on my existing valve but I need to know what terminals to check. I assume 2 of the 3 where the plug connects ?
I attached a picture of mine and here are a couple links to replacements: I couldn't save a picture from the Links.
