SOURCE: Heater will not turn on

If these are newer units 5 years or newer, there may be a thermal safety device up near the top. Follow the wires to find it. if you have this, bypass it by connecting the two wires going to it to each other and not the little disc. If this does not get the burner to ignite, then the next culprit or you do not have one then next is the pilot generator. This is the round cylinder next to the pilot flame. It and has 2 wires connecting to the gas valve. Remove it from the pilot assembly, it usually is just a clip, unscrew the 2 wires and pick up a new one. The connection on the gas valve has these wires labeled as TP for thermopile (dont ask, I don't know) replace in reverse as removed.

SOURCE: Williams wall non-elec gas heater. Black copper wire tagged thermostat?

First make sure this is a heater set up for a remote mounted thermostat. If so, the gas valve has 3 screws labeled TH (thermostat) and TP (thermopile) that's the flame sensor with 2 wires coming off it, I don't know where the goofy name comes from. there will be one screw that has both, usually the top one. Wire accordingly. The new valves have a solenoid on the bottom. this connects to the high temp. sensor up top. It has 2 wires on it, one connects to the thermostat wire, the other goes to the screw with TH and TP. Or you can skip it and connect the wire from the back of the valve to the Th and TP screw. Make sure the thermostat wires aren't pinched somewhere, thus eliminating the thermostats control.

SOURCE: MY WILLIAMS WALL GAS HEATER MAKES A LOUD BANG

Question, is this bang a metal sound or like a small poof of a gas burner? If it is a metal "bong", it is the heat exchanger expanding. You could hit the combustion chamber with a hammer causing a dent (really) and it may take the noise away. If it is a "poof", it should be looked at by a technician.

SOURCE: High Pitched noise coming from Williams Wall Heater

open it up and you'll see it while its running sounds like fan bearings or fan misalignment may need a new fan motor. if you replace the fan though make sure all power is off before disconnecting

Having problems with 35,000BTU Williams Wall Heater. Have changed thermostats twice using the 986-1R. Heater not coming on when dips down to lower temp and not shutting off when on just keeps runnin


Wall furnaces operate on millivolts of electricity, about 750 mv which is only 3/4 of 1 volt, 1000 mv being 1 volt.

The electricity is created by a pilot generator that is in your pilot assembly, the pilot generator has a hot end in the pilot flame and a cold end that is not in the flame, this temperature differential is how the pilot generator creates the 750 mv or 3/4 volt.
As this is not much voltage, it is very easily disrupted by a patina on the connections, wires and terminals, I would clean them all shiny new, this often will fix it, if not try jumping the 2 thermostat terminals that the thermostat wires are connected to, this bypasses the thermostat and wiring so if it runs you know why it was not before. The pilot generator likely needs to be replaced, you can test the gas valve with a AAA battery with a wire taped on each end, then wire the battery to the gas valves terminals that the pilot generators wired to, this simulates a good pilot generator.

If the system operates via battery do not use it this way it is not safe as no pilot safety exists in case the flame blows out! gas will still flow due to the battery powering the heaters valve, it is for testing only, if it works by battery then the pilot generators bad.

Make sure to purchase a thermostat that will operate on a millivolt system the old Honeywell t-87 would work but the new T-87 replacement ones do not work. make sure the wires are not touching each other at the connection points. Hope this helps.

Installed new wall heater and thermostat and pilot is on but heater will not come on?


What about thermostat wire? What ya got 2 wires right? Touch them together she supposed to ignite the flames then after a few minutes the fan kicks in on fan models. You got the knob on the gas valve turned to the "ON" position?

How do you turn the pilot light back on? This is an older model, probably about 10 years old or so.


Move the gas valve knob to the PILOT position and press down on the knob. You will be pressing down on a spring loaded safety magnet. Now light the pilot and keep holding down the knob till the thermocouple gets hot enough to produce electrical current and hold that spring loaded magnet in. This is your safety device. If the heat gets too hot the furnace has a fuse in line with that magnet.
When the pilot stays lit by itself without you having to hold down the button then advance the knob to the ON position. Then go to the wall thermostat and turn on the heater.

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.
