When a dryer runs but doesn’t heat, it can be an inconvenience and a sign that you need to make some repairs. Luckily, a few simple tools and steps can often resolve the issue and get your clothes drying properly again. If you don’t have the right tools, or you’re not comfortable working with electrical appliances, it’s best to call in an appliance repair professional.
The first thing to check is that the dryer is plugged in, and that the power cord is fully plugged in. If there’s no power coming to the dryer or its outlet, then it will not heat up. Make sure the plug is in securely and that there’s no damage or wear to the wire.
A tripped circuit breaker might be the culprit. Usually there are 2 breakers in a dryer, one for the motor and another for the heating element. If the second breaker is flipped, it can cause the dryer to run but not heat up. You can test this with a multimeter or by reviewing your appliance’s schematic to determine if voltage is reaching the heating circuit.
A faulty heating coil might be the problem. You can often tell if this is the case by removing the back panel of the dryer and locating metal wires that are coiled together. You can also use a multimeter to test the coil for continuity. If it doesn’t have continuity, then you will need to replace the heater coil. dryer not heating
