Question about Heating & Cooling
How do you take the cover off to get to the thermal coupling nut on top? I can't seem to get it out to replace.
Its in the bottom of the heater behind the vent cover . I don't know where you are but your local gas utility will come out and lite this for free.

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.

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!
