I'm a novice at this, but I check the system over pretty well. I can't seem to find anything wrong except its about 60 years old. Its a Lennox GS42-60S Gravity Heater. It burns natural gas, not oil.
I opened up the fan controller box. When I twist the dial counter clockwise the unit lights up properly. The off is set at 100 - the on at 150 - th elimit at 200
Is my unit running way to hot or is my fan controll dial burnt
Fixya didn;t have the manufacturer as an option or heaters for that matter, I choose AC as I'm hoping the HVAC guys are answering

Re: Old gravity Heater kicks off to early
I recommend that you begin by calling your supplier of natural gas. They offer a free service whereby they will come to your home and check out your heater. They will also show you exactly how it operates. good luck.

You can replace the wall outlet with a GFI type and cut the ac cord end off and install a basic 3 prong for 120 volt system. AC unit controls don't like ground faults and should be corrected. The cord gfi may be going out.
yes of course find how to open system an locate the coils that seems like an over heat problem with the compressor can not breath so clean the coils real good with coil cleaner ,if you dont have that just clean it for now with pressured water that will take care of your problem
That thing connected to the capacitor is a booster for the compressor .But if the outside fan doesn't work , the compressor will shutt off on overload because the high pressure in the condenser coil.
First try to replace the capacitor in the condensing unit (it's the only one that works for the compressor and the fan motor) ,but if the fan doesn't start, you need to replace the fan motor.
