How do I change heat to cool?

I don’t believe the remote tstat accepts those functions to change the fan speed versus using the on board controls. Try to change the fan speed while using the on board controls and when you have that setup then go back and change it to remote tstat setting.

I think fan should run until heating element cool off or it could overheat and break or melt parts in close proximity

There should be a fan symbol on your remote control. In the "mode" control, there should be the following options.. Heat, cool, Auto and fan. If you select fan, only the fan will run. No heating or cooling.

Try changing the the setup from gas to electric.

Over heating the engine is a serious concern. With the hood raised you should hear the motorized fan turn on just behind the radiator as the engine requires additional cooling.. If you look in from the rear of the radiator you should see the fan blades.

This electric powered motor operates on a thermostat and when the engine temperature rises this fan should come on. I'm assuming from your description that when driving and air is flowing through the radiator as the car travels the engine is nor overheating.

Check fan motor thermostat, check fan motor and check wiring.

Motor engine cooling fan only runs as engine temperature requires additional cooling.

If this is the original cooling fan it is very likely the cooling fan motor is defective or the connector to it is heat damaged from the motor problem, Make up a jumper cord from house lamp cord and hook it directly to the cooling fan motor, if the motor still turns slowly then the motor is defective.

Well, if it wasn't doing that before then you more than likely know its in your wiring. Cools down then heats back up sounds like the auto change over is on, and the heat setting is higher than the cool setting?

It seems you are low in coolant. The temperature sensor has air to sense instead of liquid and temperature gauge will be low. Try to fill up with coolant but sometimes it's hard to get rid of air from the system. Have you changed the engine thermostat?
Hope it helps

Hi, change out the faulty high limit switch thats keeping your fan off in the heat mode.
