Hello everyone! What might cause an electric dryer to run but not produce any heat? The lint trap seems fine, but clothes are still coming out cold. Are there other parts that needs inspection, or is it time to consider a replacement?

Hi DarkKnight!
No need to go for replacement yet, here are some reasons that can cause your electric dryer to not function properly:- Circuit Breakers: Electric dryers use two breakers - one for the motor (120V) and one for heat (240V). The drum can run on just one, but heat needs both. Check your electrical panel for any tripped breakers.
- Heating Element: This is a common failure point. If the element has burned out, the dryer will spin but won't heat. This is typically replaceable for $30-50 in parts.
- Thermal Fuse: A safety device that prevents overheating. When blown, it cuts power to the heating element but allows the drum to spin. This is an inexpensive fix if that's the issue.
- Thermostat: Controls the heat cycles. If faulty, it may prevent the heating element from engaging.
Most of these parts are relatively inexpensive to replace ($20-50) compared to a new dryer ($400+). If your dryer is less than 10 years old, repair is usually worth considering.

Thanks machinist! How do you determine whether it is the heating element or the thermal fuse? Can it be checked using simple home repair tools?Comment

You're welcome. Yes, you can check both parts with a basic multimeter.
First, IMPORTANT SAFETY STEP: Unplug the dryer completely before any testing or inspection.
To check the heating element:
1. Remove the back panel of your dryer (usually requires a screwdriver)
2. The heating element looks like a coiled wire in a metal housing
3. Set your multimeter to measure resistance (ohms Ω)
4. Touch the probes to both terminals of the element
5. You should get a reading between 10-50 ohms
- If you get "infinity" or "OL" (open line), the element is burned out
To check the thermal fuse:
1. It's usually a small white or black plastic component mounted near the heating element or blower housing
2. Set multimeter to continuity mode (it beeps) or resistance
3. Touch probes to both terminals of the fuse
- If it beeps/shows close to 0 ohms, the fuse is good
- If no beep/infinite resistance, the fuse has blown
