I think this valve is the problem

11 years ago

Manufacturer: ICP Heil Tempstar

SKU: GVX55 100

MPN: GVX05001

Tempstar Model: PGF030K080E

Part No: 1170430

Furnace installed mid to late 2003.

My gas furnace was blowing cold air. So when I investigated,

everything else was working fine; except no flame and no gas.

The inducer fan came on. The blower came on. But the gas

didn't come one. The pilot device glowed. I used the handle of a screwdriver to softly tap a few times on the

gas valve and all of a sudden the gas came on. It ran a

little bit then shut off. I tapped it a few more times and

it came on and stayed on this time until we shut it off.

So to me it seems I need a new gas valve.

I suppose these things can't just be taken apart and cleaned

or serviced in anyway. ~$230.00 for a new one online.

I have a call into the HVAC guy to see what he says.

I am wondering what do y'all think about it.

I think you don't mess around - it's gas, call a professional!

I called a professional. He wanted $80 just to come look at it.
I can get a new valve for ~$230 online. We just don't have
that kind of money this month. So we definitely can't
afford to pay a professional. I can change out the valve.

Just shut off the gas and the electric. Unplug the two sets
of wires. Remove the pilot tube. Undo the union connection
on the gas pipe coming into the furnace. Remove the gas pipe
coming into the valve. Remove the valve. Probably have
to remove several sub-assemblies to remove the valve. Get
a new valve. Put it all back together. Use gas tape on the
pipe connections into and out of the new valve. Use soapy
water to test for leaks. Turn the gas and electric back on.
What could be so hard about that. I have worked with gas before.

From what I've been reading online, a common problem with
these valves is some wiring connections break inside the
valve on the circuit board that controls the relays. The
connections just need to be soldered back together.
The symptoms for this problem are a lot like I described.
This would be worth looking into AFTER I install a new valve.

The valve was easy enough to remove.
Got my brother looking at the electronics on it.
He is an electrical tech.

But it looks like the whole valve needs to be replaced.

This valve was really easy to remove.
The hardest part was getting the union joint to separate.
Putting it all back together will be simple.

My brother couldn't find anything wrong with the electronics.
I put it all back together and turned it on. It came on once.
After that I couldn't get it to come back on.
I shut off the gas and electric to the unit, and I give up.
Gonna have to call a professional on this one.
I can't verify for certain that it is the valve and I don't
want to put out money for a part I don't need.
So I give up. I'll be calling a professional to fix it.

it is what you should have done on the 11th.
