Understanding the Problem
If your Maytag MD45 dryer tumbles and the motor runs but clothing stays cold, the problem is almost always in the heating system rather than the motor or belt. On gas models the heating system includes the igniter, gas valve coils, flame sensor and safety thermostats/fuse; on electric models it centers around heating elements and thermal cutouts. A blocked vent or failed safety device will also prevent heat even though the drum turns. Diagnosing dryer no-heat is a process of exclusion: first confirm proper fuel or power and good airflow, then test the safety devices (thermal fuse/high-limit thermostat) and finally the active heating components (igniter/gas valve coils or heating element). Replacing the wrong part wastes time and money, so use the tests below to pinpoint the failed component.
Common Symptoms
Drum spins normally but clothes remain cold or only slightly warm; sometimes cycles complete without heating or dryer stops early. No clicking or ignition sound on gas models, or blown thermal fuse after a short runtime.
Common Causes
- Blown thermal fuse or failed high-limit thermostat (safety cutout)
- Faulty igniter or gas valve solenoid coils (gas models) or broken heating element (electric models)
- Restricted venting / poor airflow causing overheating and tripping safety devices

Helpful Repair Tip
Before buying parts, check the exhaust vent for heavy lint restriction and test the thermal fuse for continuity with a multimeter — a blown thermal fuse is the most common single cause of no-heat on MD45 dryers.
Frequently Asked Questions
How do I check the thermal fuse on a Maytag MD45?
Unplug the dryer first. The thermal fuse is usually mounted on the blower housing or exhaust duct. Remove the back panel or lower front panel to access it. Visually inspect for a broken or burned fuse. Use a multimeter set to continuity/ohms: remove one wire from the fuse and check for continuity across the fuse terminals. No continuity means the fuse is blown and must be replaced. Also check the vent — a clogged vent often causes the fuse to blow.
Can I replace the igniter or gas valve coils myself, and what will it cost?
Yes — if you are comfortable working with basic tools and have turned off gas and power, you can replace the igniter or coil kit yourself. Typical parts cost: igniter $25–$70, gas valve coil kit $30–$80, thermal fuse $10–$25. Labor at a repair shop typically adds $100–$250 depending on your area. Always verify the exact part number for your MD45 before ordering, and if you're unsure about handling gas connections, hire a licensed technician.
