Understanding the Problem
If your MDE5500AYW dryer tumbles but doesn't produce heat, the issue is usually a failed heating component, a safety device that has opened, or an electrical supply problem. Electric dryers require both 240V supply lines and a working heating element/relays; gas dryers need a working igniter, gas valve, and safety controls. Many failures are simple, like a blown thermal fuse or broken heating coil, and can be diagnosed without removing the whole cabinet. Begin troubleshooting by confirming that power is present (for electric: both hot legs) and that the dryer drum turns normally. From there, the typical suspects are the thermal fuse, heating element (or igniter/gas valve on gas models), thermostats/thermofuses, and sometimes the control board or timer that switches the heater on. Use a multimeter for continuity checks and follow safety steps — disconnect power before opening the dryer.
Common Symptoms
Dryer runs and tumbles but clothes remain cold or barely warm; sometimes trips circuit breaker (electric) or runs briefly then shuts off; unusual smells or visible broken heating coil; longer-than-normal drying times.
Common Causes
- Blown thermal fuse (safety device that opens if overheating or blocked venting occurs)
- Open or broken heating element (electric) or failed igniter/gas valve (gas)
- Faulty thermostats, cycling thermostat, or control/relay not supplying power to heater

Helpful Repair Tip
First check the thermal fuse with a multimeter for continuity — it's the most common single-part failure. If the thermal fuse is open, replace it and also inspect the venting and heating element for cause of overheating.
Frequently Asked Questions
How do I test the thermal fuse on my MDE5500AYW dryer?
Unplug the dryer. Locate the thermal fuse (usually on the blower housing or near the heating element assembly). Remove the wires and use a multimeter set to continuity or ohms. A good thermal fuse will show near zero ohms (continuity). An open circuit (OL) means the fuse is blown and should be replaced. Note: thermal fuses usually blow because of restricted venting or overheating — clear lint and check the vent before replacing.
Can I replace the heating element myself and how hard is it?
Yes — replacing an electric dryer heating element is a common DIY repair if you are comfortable with basic hand tools and safety. Always unplug the dryer first and, if possible, disconnect 240V at the breaker. Access is typically from the rear or by removing the top/front depending on model. Remove the element housing, swap the coil assembly, and reassemble. If you're not comfortable with electrical work or the element is not the root cause (for example a bad control relay), consider a technician.
