Where can I get a Technicians Manual?
Expert:  BillyHvac replied 1 year ago.

Unfortunately I do not show that this unit is supported with a service manual. I can tell you that if the thermocouple is new,, and pilot will not remain lit after button release, then the valve is bad. Does pilot light but goes out on release?

Hello, the company charges extra for phone calls, I will submit that offer, but it is optional, we can continue here on your original deposit if you do not want to pay for a phone call.

Meantime tell me if the gas valve has ON, OFF and Pilot positions, and how long you are holding the knob down in the pilot position after the pilot is lit.

We can go from there.

The gas valve has ON and Off settings. I have held it for 60 seconds.
Expert:  Phil replied 1 year ago.


In that case the gas valve is most likely bad, about an 80% chance of that.

If you want a further diagnosis to insure that the gas valve is indeed bad

Please attach a well focused, close up photo of the wiring diagram glued inside the service panel, the picture needs to be taken from straight on, in very good light.

You can use the paper clip- icon at the right end of the tool bar at the top of this dialog box to attach it here.

If you have an error code showing, tell me what the code read out is on the wiring diagram or a sticker next to the diagram please.

If there is no paper clip-icon, look for the '+attach files'link at left of your send button.

I can mark it up with trouble shooting instructions.

You will need a multi meter ($30 at a hardware store) and some experience working with appliances, let me know a lot about your skill sets in those regards.

We can go from there.
