I have a nat gas Williams wall heater with an electronic thermostat. The heater is 15+ yrs old but works well when it comes on. Sometimes it won't come on until you touch the on/off switch on the thermostat. Just touch it, it's like your body touch completes the circuit or something? I've put fresh batteries in the thermostat and replaced the vent safety shut off device. Any ideas? Thanks

Tameka, what you described sounds like the Thermocouple or Thermopile is failing. If your heater is a Flue-less heater, the Oxygen Depletion Sensor (ODS) which is part of the Pilot assembly, may simply need cleaning. Any of the causes I listed are repairable and would require a service technician to do it.
sounds like the gas valve may be failing .... possibly a small leak in the diaphram of the gas valve...
what your describing i to would start with the thermocoupler and usually that would correct the problem,but if you have done that and it still is shutting off and you are not getting any drafts that would cause the pilot to go out .then i would say the gas valve is your problem and it is intermetent failing....
Hello Try a "breaker bar" on the end of the pipe wrench.Good news is that the control threads are BRASS and the tank is steel,meaning the control will always come out (without spray oil).Counter clockwise is correct.Have faith and lay into it!
Turn the power off to the Air handler unit.
Remove the thermostat from the wall, (Just the face part).
Look on the back side of the thermostat and verify that the jumpers are set to electric and not gas, otherwise the fan will not run during heat mode, they come from the factory usually set for gas.
If this is a electric heater this will solve your problem, If it is gas then it will be more detailed. Once you put it back on keep in mind that most thermostats have a 3-5 minute delay so just give it a little time and the fan should then work once you have the jumpers in the correct position.
