SOURCE: Carrier Furnace 58gs075-1 Circuit board issues...

I cant see your wire diagram but trace the circut your talking about. I believe it usually goes through a series of safety switches. Put your VOM across each individual switch. If you get 24 out from the board the first 1 you check and get 24v is open and not feeding back to the board is out. FIND out why. the switch could be bad but it may be indicating a more involved problem, just look aroeund for chared wires or tell tell signes of flame roll out or if its an open (fuse link) suspect what can cause an over heat condition anythign from a bad board or too long an off cycle before the indoor fan comes on ect. PONIT IS Once you come across the cause may not be the reason.
Please grade me accordingly and if you need more I need more info from you.

Pilot won't stay on Williams wall furnace 4007732, changed therocouple already


Before replacing the gas valve, make sure that the limit switch is not tripped. I have seen techs wire the limit in so that the pilot will also shut off. The limit is usually at the top of the heater or mid way down, behind the casing. As for replacing the gas valve, you can replace it with a universal combination gas valve, they have multiple brands that can match pretty close to your valve. They can run over $100.00 easily and here, you have to have a contractors license to buy one. Hope this helps! Happy Holidays!

I've got a 23 yr old 30DV3 whose pilot light works, and the thermostat & heating element seem to work, but not well. With the thermostat set at full hot, it just barely throws out any heat at all. ...


As I'm sure you already know, Empire Comforts Systems, no longer makes that model heater and hasn't for some years, now. I mentioned that, because if your unit needs parts, they may be almost impossible to get. In any event, there are a several things that may be causing the problem.

  • Low Gas Pressure - Burner is not receiving enough gas. Check for obstructions and have gas pressure at the unit checked.
  • Clogged burner or air intake (venturi valve) is partially clogged. Clean burner ports and venturi valve.
  • Gas line Shut Off Valve at heater not fully open. Check Gas line Shut Off Valve.
At 23 years old, you've gotten your money's worth out of this unit and it may be time to replace it. Empire makes several Direct Vent Wall Furnaces that are rated as High Efficiency Furnaces. In the long run, the money saved in fuel cost, would be worth installing a new one.

Hope this helps you solve the problem.

Furnace lights right up, but will not shut off with on-off switch or thermastat switch? checked out the thermastat switch and that works fine.


Disconnect the thermostat wires from the gas valve, if unit still runs; you have a short in the gas valve and it needs to be replaced.

I have an early 80's mobile home with an "intertherm gas atmospheric furnace" pilot light is lit but can't get the furnace to "fire". Seems as though the limit control is stuck open. ...


If your pilot light is lit then I would first check your thermostat. Make sure it is on heat setting and fan is on auto, turn stat up to where it should be calling for heat. If you don't get burner to light remove front cover from thermostat and see if it has a mercury switch, if it does move temperature selector up and down and see if you can see a spark in mercury switch vial. If y ou cannot see a spark remove screws that attach t-stat to base.Remove carefully and disconnect wires that go to r and w terminals on stat base. Temporarily connect these two wires together. This should make burner light if you have power to thermostat. If burner does light disconnect wires and replace thermostat. Also if you have a volt meter check across these two wires and see if you have power there. Should be around 24 volts a.c. If your thermostat has a fan on setting try that. If fan runs you know you have power to furnace The gas valve needs 24 volts to operate and inside the electric control box in furnace there is a transformer to step down 110-120 supply voltage to 24 volts. If transformer is working you should be able to hear a low buzz or humming sound. You can also check across gas valve terminals when t-stat is set for heat, you should read about 24 volts. If you have 24 volts to gas valve and it is not opening then you need to replace gas valve. The main purpose of the limit switches is to turn blower on when temperature in heat exchanger reaches fan on temp,shut off blower after burner shuts off and heat in heat exchanger reaches fan off temperature, and limit if temperature exceedes set point without blower coming on. I hope this helps you. Thanks
