furnace problem

[dave]

I have a 1992-installed Rheem RGLG-05EAUER forced-air furnace on my second floor equipped with a Honeywell VR8204 gas valve I believe is original. The problem I have is intermittent, and logic tells me it is a clogged valve that sometimes becomes unclogged. Any advice is appreciated. Please help. Here is the sequence of events that illustrates my problem:

1. Reset Thermostat
2. Discharge inducer immediately engages for about a minute.
3. Igniter burns red hot.
4. No ignition.
5. Blower motor comes on for a few minutes and then everything shuts down.

Everytime I fiddle with the valve, rapping it gently with a screwdriver or flipping it on and off, I seem to be able to reestablish gas flow temporarily. When that happens everything works great for a while, but the problem always comes back.

Logic tells me there may be an obstruction in the valve that I temporarily shake loose by fiddling with it. Please let me know if any of you have experience with this. Thanks

Just keep wacking it with a screwdriver.

Eventually the problem will be solved.

One way or another.

It's not an intermitant blockage. It's either a bad board or a bad gas valve. Once the igniter is hot, do you get 24v to the gas valve? Do you smell or hear gas? Hear a click and no gas? Replace the gas valve...

You need to replace the thermostat. Its almost always the thermostat. Bubba

Try greasing the valve.

Bubba, I used to believe you but my research shows it's almost always the wiring. Wireless is the the way to go, go WAP.

nope.... try again

BTW... check **all** the safeties to make sure they are operating properly too.

Maybe if you put the correct valve in and adjusted it properly??
