Parts That Fix Maytag Dryer MED7230HW3 Not Heating

When connected to electricity the dryer heating element glows red hot and generates heat. When air is blown over it, it heats the air which is used to dry the clothes. The heating element fits inside the heater housing inside the dryer. Wear and tear on the heater coil from use will eventually cause the coil to break and the element to fail. When this part fails it can cease to produce any heat. Alternately, the coil could break and short to ground allowing the dryer to continue to heat even when turned off. The latter is a fire hazard and the dryer should be disconnected from power until the element is replaced. If the element coil breaks, the element needs to be replaced. This model is 11 by 5 inches with 5/16” terminals, metal and ceramic, and comes in black. It is sold individually.

The internal-bias thermistor (Thermistor, Dryer Thermister, Dryer Thermistor) prevents the dryer from overheating by monitoring and controlling the temperature of the inside of the dryer drum. It is located on the blower housing, next to the thermal fuse. If your thermistor is defective, drying time could be prolonged or you could get a fault code. You could also notice your dryer overheating. You can test the outlet thermistor on a multimeter, it should read 10Kohms (10,000 ohms) of resistance at room temperature. It can tolerate 10% fluctuation. If your reading indicates the part is defective, it will need to be replaced. This model is white plastic. It is sold individually.

The thermal cut-off (fuse) is meant to trip at a higher temperature than that of a high limit thermostat. This is a one time use fuse, so when it does trip, you must replace it. The hi-limit thermostat acts as a safety mechanism that keeps the dryer from overheating. Once the dryer temperature reaches a certain point, this piece will shut down power to the heating element.

This is the moisture sensor for your dryer. It helps detect the amount of moisture in your clothes during the dryer cycle. If you notice your clothes are still wet after an automatic dryer cycle is done, you may need to replace the sensor. You will find the moisture sensor behind the lint screen. Be sure to disconnect the power source from the dryer before you begin this repair. Note: Some model's require two sensors, please order quantity needed. Sensor only, harness is not included. This part is sold individually.

This authentic OEM high limit thermostat is made for your dryer. It is an important dyer element, because it will automatically shut off the heating element when it overheats. Be sure to disconnect the power to your dryer before you begin this repair.

This is a manufacturer-made thermal fuse for clothes dryers. The thermal fuse is a safety component within dryers to shut off power to the heating element if the temperature rises above a specific temperature threshold. If your dryer is experiencing problems heating up or starting, this thermal fuse may be bad and likely needs to be replaced. Replacing this thermal fuse may require some disassembly of your dryer but should only need a screwdriver and wrench. This thermal fuse is sold as an individual OEM part and does not come with any other accessories.
