    No, the thermostat is on the wall, separate from the heater. It's like this:

Is this one of those heaters that has the thermostat down on the bottom by the gas valve, and not mounted on the wall somewhere?

Williams wall heater, lite pilot and heater comes on okay, but will only come off when I disconnect the thermostat?


If you have to disconnect the thermostat wire at the gas valve then it is either a shorted thermostat or a short in the thermostat wire.

If you only have to disconnect the thermostat from the wire, then it sounds like a bad thermostat, replace the thermostat

Williams 3003622 pilot light is on but heat doesn't turn on- there is a "Do It" thermostat connected. Is it a problem with the thermostat or furnace?


Try jumping out the thermostat (red and white wires) that run to the thermostat these tell the heater to come on. Jump them together if you have heat it is the thermostat, if no heat it is the furnace. Should it be the furnace I would first check the thermocouple or some manufacturers call it a flame generator. Clean this with steel wool and position it in the top center area of the flame as this is the hottest part of the flame. Good luck

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.
Good Luck,

I have a Williams Ceramic Gas Wall Mounted Panel Heater, the pilot is on but the furnance is not working


Jump the two wires going to the thermostat, if it starts , you have either a bad thermostat or a broken thermostat wire. If it does not fire up, you will need to check for 24 volts AC going to the gas valve from the transformer. If you have voltage, you have a gas valve issue. If no voltage, check for a limit switch that may have overheated with an Ohm meter. If they all test good, replace the transformer.

We have a Williams wall heater that was gas/ converted to propane that is newly installed. The thermostat does not work. Any suggestions?


Assuming the pilot is lit, try jumping out the thermostat wires where they come into the valve. A paper clip would work. If it works, the problem is in the t-stat circuit.

The pilot goes on and stay on but heater doesn't the thermostat its ok


Take the two wires going to the thermostat and cross them. If the unit starts, you have a bad thermostat. If it doesn't, at the heater put a jump wire across the terminals where the thermostat wires are connected to. If the unit starts, one of the wires going to the thermostat are broke. If it still doesn't start you may have a bad transformer. Check for 24 volts AC across the two terminals on the gas valve. If yes, bad gas valve. If no, bad transformer.

can you manually fire the unit w/o the thermostat by shorting 2 of the 3 wires, there may be more wires than that, but you should be able to fire it on 2 to 3 wires alone let me know it sounds like something is floating voltage wise on the unit

Honeywell Thermostat RTH7400D


The thermostat will not cut off the A/C until the thermometer reading gets to 76.

If there is not a heat source near/behind the thermostat which is causing the thermometer to read higher than actual room temperature, it sounds like the thermostat thermometer is out of calibration.

There are ways to calibrate it, but much to involved to go into here.

One solution is to just set the thermostat at 80, knowing that it's really set on 76.

Another solution is to replace the thermostat.
