What makes a heater only work on the highest setting?

Heater only works on highest setting. It’s the blower motor resistor. 12 volts direct to the motor is high speed. The resistor gives you the slower speeds and has a thermal breaker that is blown now.

How do you turn on a high speed heater fan?

What are the disadvantages of an electric room heater?

They operate with considerable noise caused by the fan. They have a moderate risk of ignition hazard if they make unintended contact with furnishings. Their advantage is that they are more compact than heaters that use natural convection and are also cost-efficient for portable and small room heating systems.

What happens when you turn on an electric heater?

When you turn a heater on, the electrical current that is produced heats up the nichrome wire components — better known as the heating coils — in the unit. Electrical energy is turned into heat as the current passes through the resistor. That’s why electric heaters are also known as resistance heating units.

Can a space heater heat a whole room?

Why does my car heater only work on one speed?

If it doesn’t light up or you only have a high fan speed then your resistor block needs replacement since it is bypassed on high speed. If the resistor block tests out good and you don’t have any fan speed or a slow fan speed for all speeds you can assume that the blower motor is at fault since everything else has tested out ok.

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 heater only work on one speed?

On low the voltage will travel through all of the resistors which would be 4, on medium low it will travel through 3 of the resistors, on medium it will travel through 2 of the resistors, on medium high it would travel through 1 of the resistors, and on high it will bypass the resistors and just send direct voltage to the motor.

How can I tell if my car heater is working on any speed?

Connect the leads to the battery posts and check DC Voltage. You should have a reading greater than 12.4 volts this will designate a charged battery. You will then want to move your dial to see what speed the fan works on and whether it works on any speed.
