Re: wall heater does not work
I can only make assumptions on your setup based on your description. I am assuming you are referring to a gas wall heater that has an electronic ignitor and that you shorted the thermostat wire leads together to simulate 'calling for heat' .. If that's correct, then here's a few things you can try.. If you can open the wall heater access panel to see where the burner is, you should see some kind of igniter there too.. Rather than short the wires at the thermostat, why not ,...make a wire jumper at the heater itself and short across the contacts of where that thermostat would plug in? By doing that, you take the wiring out of the equation.. A short across the thermostat terminals at the heater should turn th eheater on and call for heat.. If everythings working, you should get gas into the burner and the ignitor should provide a spark to get a flame established.. I hope I helped you.. if not.. please elaborate on whats actually happening or where I am wrong..

It could be, here is what I do to verify that the problem is in the thermostat. Remove the thermostat from it's mounting plate, you should now be able to see the wiring for the thermostat. Locate the red and white wires, they usually run the control for the heat, now place a jumper to join the red and white wires. The heater will now run with out a thermostat, if it runs yes it is the thermostat, if not you need to look in to the control side of things. This means either good electrical trouble shooting skills or time for the repair man.Good luck
The first thing I would do is have gas pressure checked, check pressure on the outlet side of regulator. Your gas supplier should do this for you for free or for minimum charge. It sounds to me like you have high pressure problem. I hope this helps. Thanks
Hello my name is Heath it will be my pleasure to assist you. The problem then seems to be with the thermostat. If you have an ohm meter you can verify by attaching the ohm meter to the thermostat and turning it up if there is resistance when the thermostat is turned up then the thermostat is okay if the resistance is infinite then the thermostat is not working.
If it touched a grounded metal surface, it is possible, leave the wires hooked up at the furnace, pull the thermostat off of the wall, disconnect the 2 thermostat wires, and then twist them together, the furnace should fire, if it does, then the thermostat is shot. Replace the thermostat, usually when there is a short, it burns out the heat anticipator on the thermostat.
Make sure you get the t-stat back on the wall exactly as it was. It needs to be level for it to work properly. Then turn off the power to the furnace for a minute or so, then turn it back on. This will reset any faults that may have locked it out.
If this still doesnot work then you may have shorted the wires. Often on old systems the wire coverings are bad and if the bare wires touch any metal or even sometimes each other they can short out the transformer. If the transformer is dead them nothing will work. I'm afraid you may have done this inadvertantly.
Yes, but it will require some knowledge of electric to do that. You will need a line voltage thermostat and mostly like have to have that run a contactor that will be wired to bypass the heater thermostat. A good electrician should be able to to this for you very easily.
If the unit has a wall thermostat, remove one of the wires from the thermostat. If the unit stops it indicates a bad thermostat. If it continues to heat, remove one of the wires coming from the thermostat going to the gas valve inside the heater. If it continues to heat you have a bad gas valve. If the heater shuts off, you have a bad thermostat wire (short).
