Check the condenser and evaporator to make sure these are clean. If the filter is not replaced or cleaned regularly the evaporator will become plugged.
If this is a roof top unit the thermostat may have a thermocouple on it that is shoved into the evaporator. Some times these go bad.

Air conditioners running into a small space tend to cycle rapidly. Try to direct the airflow away from the intake so that no cold air reenters the unit. This will allow more cooling before the thermostat cycles.

How do I fix my Trane air handler to keep it from turning off about 20 seconds after being commanded to turn on?

Some units require both a start and a run capacitor. It's possible the wrong capacitor was replaced. It's also possible to add a run capacitor to a system to keep the fan running. There is an outside chance the bearings in the fan motor are worn to the point it's time to replace the motor.

Do I have a wiring or other easy to fix problem or must I replace thermostat? My Totaline 0441 thermostat (installed in 2004) turns fan on as programed but just suddenly stopped producing HEAT.

It is possible that it is the Thermostat but more likely the heat source the thermostat is connected to. Set the thermostat to heat to as high as it can go. If the heat source does not come on in a few minutes you likely have a problem at the heater which may be a simple loose or burnt connection in the wiring or something more serious.

Sounds like thermostat is failing. There is a factory set resistor that helps the thermostat keep a 2 degree accuracy. Second possibility is that you have a fan or direct airflow from the cooling system, being devirted, that is allowing the cool air hit the thermostat on the wall.

I have a LP gas log heater, the thermostat is in the living room and I would like to shut this room off this winter. Is it possible to add a second thermostat elsewhere in the house so this can be done?

Yes. If the thermostat is connected with electrical wires you can buy some wire and move the thermostat or add a second thermostat. Just be aware that dual thermostats can cause people to forget that they have to shut both of them off to stop the heater.

So your point is? Just make sure the wires going from your fused outlets to the 50-amp outlet plug is the size wire# 8--or #6 with ground.
