Why is my heat exchanger not turning on?

A dirty blower motor can lead to equipment failure. The heat exchanger won’t work unless enough cool air moves across it to keep it from overheating. When the motor is dirty, the heat exchanger isn’t exposed to enough moving air.

What does it mean when your heat pump wont turn on?

Whether you’re using a heat pump or a gas furnace, broken equipment means it’s time to pull out the space heaters, put on thick jackets, and endure a whole lot of discomfort. At least until your HVAC guy shows up. But why doesn’t your heat turn on?

Why is my blower motor only working at high speed?

The first thing that needs to be determined is the type of noise that is present and the possible sources. Rattling or knocking noises while… The blower motor only working on high speed is a common symptom of a failing blower motor resistor; but the fact the radio stopped working at the same time is unusual.

Why is my car’s heater not working properly?

Blockage – The heater core is made up of many very thin tubes of metal, and if it becomes blocked the coolant may circulate as normal around the engine, but not flow through the heater core.

What happens if the blower motor only works on high speed?

In other designs, the failure of 1 resistor means you lose only one speed. However, most car makers bypass the blower motor resistor completely when you move the fan speed switch to high. If your blower only operates on its highest speed, chances are you have the series type of blower motor resistor. This is the most common failure mode.

Why does my air conditioner heater not start?

No, the heater ignites, but the fan still doesn’t start. That’s not good… It could be a bad run capacitor or it could have a worn motor bearing that won’t let it start. Switching to fan “on” also doesn’t get it to start.

Why does my Ricks free auto blower motor not work?

A clogged cabin air filter reduces airflow through the ducts, increases current draw on the blower motor and can cause blower motor resistor overheating and premature failure. If you replace the resistor and it burns out again, check the current draw on the blower motor.

What causes a blower fan to not work?

When this happens, you may notice that you will not feel anything blowing out of the vents at all. This may also cause the blower motor to work intermittently. A blower fan is connected to the negative battery terminal (also called ground) on one end and to the positive battery terminal through a blower motor resistor on the other end.
