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: Wall furnace model # SFB50146B Thermal Coupler. Does it have 2 wires?

if the pilot light stays lit, but the burners don't kick on, it's a problem with the thermostat or thermostat wiring, or a problem with the valve inside the gas actuator

SOURCE: How to reset vent safety switch

the reset is at the top left side of the furnace. take the cover off n press the red button. the switch could be failing but CHECK drafting through the furnace. hold a flame at the top of the furnace n make sure its pulling inward. u could have a blocked vent pipe or vent cap which will cause excessive heat n tip the safety switch. good luck!

Chimney type wall furnace. The furnace won't start However after switch was off for a couple hours and turn on the switch it started. What is a possible problem?


The problem sounds like the thermocouple is not working correctly. After being off for a couple hours allowed it to cool down and reset. Sometimes you can clean the soot build up from it and it will work again. Sometimes they just need replacing. the thermocouple is what the pilot light flame heats up when you turn on the heater. when the thermocouple gets hot it sends a 20 to 60 millivolt signal to the gas valve to activate the gas flow to the main burner.

Rattling expansion and contraction noise, seems to come from header area toward top of heater


I would suggest an insulation foam. Should help to reduce the rattling and some of the expansion pops. Or you could brace the ducting, ducting is very thin metal and moves fairly easily if built real loose.

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,

Assuming the pilot is clean and sharp. Before replacing the valve, clean any spade connections, those going up to the spill switch in particular. Clean and tighten all 4 connections. Good luck.

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

Unable To Keep Pilot Light Lit!


I have a Williams top vent gravity wall furnace (model 5009622) and I had the same problem. I had to take the cover off the furnace -- screw on top and two at the bottom (open the access door and there is one screw on each side) to get to the reset button for the vent safety shutoff system. On my furnace it's on the left side toward the top of the unit. I pressed the little red reset button and it's been working ever since. If your furnace is properly installed and doesn't have bird's nest in the chimney, it should work fine. Good luck!
