Gas and Oil Home Heating Furnaces - Goodman Dependable 92

I have a dependable 92 in my house and its blowing only cold air. Any ideas why? The gas works in the rest of the house. What could it be? Thanks!

Dependable 92 is the marketing name, not the model number of this Goodman furnace. Pls check the nameplate and provide its complete M/N

Is the burners coming on?

Any fault code (if any) on it?

Did you try to at least see if it makes another attempt at ignition (while you stand down there with the big furnace cover off to observe) by turning off the furnace for a number of seconds and then turn it back on again to let it reset itself?

Hi Folks.

Just joined the forum here. Was Googling for "Goodman Dependable Ninety Two," a contrary, not-so dependable furnace at my old house, and found this forum and this thread. I see that the OP has not yet responded.

Reading the thread, I gather that I need to translate the product name into a model number, so I will as soon as I get back over to the house, which I am fixing up to rent.

Anyway, the furnace was working well until a week or so ago. I turned it on routinely while working over there. Then two days ago it just did not come on at all when I turned on the thermostat (an old Honeywell round one). I had the gas company check the gas, and it is present. I had smelled a faint leak at the meter outdoors, but that was not the problem. Just a bit of trash in the regulator, said the gas guy, and who fixed that on the spot.

Together, he and I looked at the furnace to try to start it. It has an electronic starter, no pilot light. Nothing happened. No fan. No glowing starter. No nothing. We checked the fan-only feature at the thermostat. The fan runs. Power is getting to the furnace. The gas guy said "You've got a furnace problem." I agreed. He left.

By tricking the door switch to the lower section, I could see that the circuit board diagnostic light stays on continuously, and it does not blink at all, except for one short blink when it first powers up.

I powered off at the main breakers. Then I carefully removed and reseated each of the spade connectors, one at a time, on the furnace's control board, and anywhere else they went that I could reach, wondering if corrosion might have caused one or more to be intermittent. That made no difference whatsoever.

I noticed that after powering up, that after some seconds I could hear a relay on the board click, but nothing visible or audible followed the clicking relay that I could tell.

And that's when I started Googling and landed here. I wonder if any of the Membership here has been through this before.

Happy day.

Make sure thermostat not shot by jumpering R to W down in furnace where 24 volt AC/stat wires all hook up. I had one recently that fooled me into thinking the sequencer or heat relay to the inducer was down, and here it turns out the tenant had shifted the anticipator to some position where there was no contact! A burned out one can cause same thing. When you get the new Honeywell stats, they warn not to set the heat anticipator lower than correct furnace amp draw (often about .4), as if it is too low, the anticipator can burn out. !

If that is not it and you know that you are getting 24 volts through the W terminal by either jumping or voltmeter testing between that terminal and to metal ground, then you may have either a sequencer or heat relay burned out, or even the inducer motor itself burned out, if it don't run. if it hums, it is seized up.

Greetings, Forum.

Thanks, ecman51.

That's what it turned out to be. Thermostat was okay. 24V ok. 115vac okay too. Burned relay contacts. Switched out circuit board for a newer, improved one. Works again.

Thanks a million for your guidance.

BTW, I gather that Goodman is a sort of basically okay brand, but not the cat's meow for dependable. I am curious what brand would be best for replacing the "Goodman Dependable Ninety Two" when it is time to swap. I am thinking of low trouble, and ease of service over time.

Happy day.

This morning, the fan is blowing cold air and the burner is not coming on. Tried to turn of electric and gas to the furnace for a few seconds and turning on, but no burners and this does not have a pilot.
Any sugestions

Hello jitin,

My suggestion would be to start a new thread and to post the model of your Goodman furnace, which you can obtain from the rating plate in the burner compartment of the furnace.

And copy and paste your last thread as well.

It's 'way too confusing trying to deal with multiple problems on one thread.
