I have a carrier...

I have a carrier model 58PAV090-14 furnace that is showing a code 12. The blower motor comes on for about 90 sec then shuts off. Then the exausht motor kicks on then the glow igniter comes on but no gas comes on to ignite then the furnace just shuts down. Can you please help the wife is freezing?

Contractor's Assistant: Did you check the furnace's filters?

Yes just changed them

Contractor's Assistant: Do you plan on doing the work yourself?

I hope so I have been able to fix every other problem just need help with the diognostics.

Contractor's Assistant: Anything else we should know to help you best?

Furnace is over 20 years old

Code 12 is normal after power is interupted, main blower will run 90 sec before restart when t-stat is calling for heat.

This time put t-stat to off then reset power then set t-stat to heat, raise temperature, wait till it fails, THEN get the true error code. It will be either 31, 33, or 34

Same code 12 before and after. I have attempted to send a video but it just locks up the website and won’t let me send it

OK, when hot surface glows, mesure voltage for 24Vac at gas valve to see if theres power, you should even hear the gas valve do a clicking sound when it energized.

Spiked to 24v when exhaust motor kicked on then stayed at 18v until end of cycle

Good, it goes down to 18 because of amperage draw.

Does Gas valve click when energized?

No

OK

Its getting power, selenoid valve is drawing but not opening.

Sorry but It would appear to be a defective gas valve.

Does the whole gas valve need to be changed?

Yes, no parts sold seperately

It was not the gas valve. Same damn problem

You said it was getting 24 v on demand ?

so gas should come out if gas valve is good.

Did you check gas pressure inlet pressure? is there any gas coming out?

If its propane, it may be empty tank or bad regulator, or a valve is shut off

Yup checked all. I am changing the circuit board! I am mentally exhausted.

OK..........

Ask Your Own HVAC Question

There is a inlet and outlet gas pressure tap on the gas valve to check pressure. I would check that before installing a new control board.
