The reasons below, which occur when the dryer does not heat up, are listed from most likely to least likely. Check or test each cause, starting with the most probable cause.
The thermal fuse is a safety device designed to protect the dryer from overheating. The fuse is located on the blower housing or on the dryer heating source, such as a heating element (heating element) on electric dryers or on a gas burner on gas models. The fuse must have continuity, which means that current can flow through it. If the fuse overheats, it will blow and the continuity will be lost. A multimeter can be used to check its integrity. Note that a blown thermal fuse is an indicator of limited ventilation from the dryer to the outside. Always check ventilation when replacing a blown thermal fuse.
Gas valve solenoid
Gas dryers have two or more solenoid coils. The gas valve solenoids open the gas valve to allow gas to flow into the burner block. If the solenoid fails, the burner may operate intermittently. If the burner continues to shut down, the dryer does not heat up enough and may not stop. To determine if one or more of the gas valve solenoids has broken, check the igniter. If the igniter glows and goes out, but does not ignite the gas, then the gas valve solenoid is faulty. If one or more of the gas valve coils are defective, we recommend replacing all of them in the kit.
An electric igniter (igniter) uses heat to ignite the gas in the burner assembly. If the igniter does not work, the gas will not ignite and the dryer will not heat up. To determine if the igniter is burnt out, use a multimeter to check its integrity and if it is broken, replace it.
Heating element block
The heating element block heats the air before it enters the dryer. Over time, the heating element may burn out and the dryer will not heat up. To determine if the heating element block has burned out, use a multimeter to test for continuity and replace if broken.
On a gas dryer, a flame (fire) sensor detects heat from a fire. If the flame sensor does not work, the dryer will not heat up. Before checking the flame sensor, first make sure that the igniter and thermal fuse are not causing damage. To determine if the flame sensor is defective, use a multimeter to check its integrity at room temperature. If the flame sensor is not continuous, replace it. Br> Heating element
The heating element (heating element) heats the air before it enters the dryer. The heating element can burn out over time. If the heating element does not work, the dryer will not heat up. To determine if the heating element has burned out, use a multimeter to check for continuity and if it is broken, replace it.
Incoming power problem
If your dryer does not heat up, you may have a problem with the power input,. It often happens that only one fuse is turned off, which leads to the fact that the dryer can work, but does not heat up. Check the fuse box or circuit breaker or measure the output voltage with a multimeter.
High limit thermostat
High limit thermostat monitors the dryer temperature and shuts down the burner if the dryer overheats. If the high limit thermostat is faulty, it can shut off the burner even if the dryer does not overheat. However, this is rare. Before replacing the high limit thermostat, check for increasingly frequent breakage parts. If you have determined that all other components are working correctly, then check the thermostat with a multimeter for continuity and if it is broken, replace it.
Thermostat with a cycle
The thermostat with a cycle periodically turns the heating on and off to regulate the air temperature,. If the thermostat is defective, the dryer will not heat up. However, this is rare. Before replacing the thermostat, check for increasingly frequent breakage parts. If you determine that all other components are working correctly, then check the thermostat with a multimeter for continuity and if it is broken, replace it.
Main control panel
The main control board (control panel) may be faulty. However, this is rare. Before replacing the main control board, check for more and more breakage parts. If you have determined that all other components are working correctly, then replace the main control board. (The control panel is difficult to test, but you can try to check it for signs of burnout or short circuit.)
Если сушилка не нагревается, то может быть неисправен таймер. Однако это бывает очень редко. Перед заменой таймера проверьте все более чаще ломающиеся детали. Если же Вы решите, что все остальные компоненты работают правильно, то проверьте таймер с помощью мультиметра и ознакомьтесь с электрической схемой. Если таймер неисправен, то замените его.
