Understanding the Problem
If your Whirlpool/Maytag-style DV455EVGSWR dryer tumbles but produces little or no heat, the problem can usually be traced to a few common components or to a power/venting issue. Electric dryers require both proper 240V power and functional heating elements, thermal safety devices, and thermostats to generate and regulate heat. A failed heating element, a blown thermal fuse, a faulty thermostat, or an electrical supply problem are the most frequent causes. Before replacing parts, perform basic checks: confirm the dryer is receiving full 240V (two hot legs) at the terminal block, inspect and clean the exhaust vent and lint screen, and test suspected components with a multimeter for continuity. Many no-heat problems are resolved by replacing a single inexpensive part (thermal fuse or heating element) or by clearing a clogged vent that caused an overtemperature cutout to blow.
Common Symptoms
Drum tumbles but clothes stay damp or cold; dryer runs but no warm air; longer-than-normal drying times; sometimes trips a breaker or blows a fuse.
Common Causes
- Blown thermal fuse (most common safety cutout when venting is restricted)
- Failed heating element assembly or open heater coils
- Faulty cycling thermostat, high-limit thermostat, or heating relay on the control board
- Insufficient electrical supply (missing one hot leg / 120V per side means no 240V heat)
- Severely restricted venting/blocked exhaust causing overheating and cutouts

Helpful Repair Tip
Start by checking the thermal fuse for continuity with a multimeter—if it's open, replace it; also run the dryer on a short cycle with the vent disconnected (careful) to see if heat is present, which helps distinguish venting from element/control issues.
Frequently Asked Questions
Can I replace the thermal fuse or heating element myself?
Yes—these are common DIY repairs if you have basic tools and follow safety steps. Unplug the dryer and, for electric dryers, also turn off the circuit breaker. Access the rear or front panel per your model's service instructions, remove the old component, and install the replacement. Always verify the part number for your DV455EVGSWR and test continuity before and after. If you are not comfortable working with electrical components or removing panels, hire a qualified technician.
How much will it cost to fix a DV455EVGSWR that won't heat?
Part costs vary: thermal fuses are inexpensive (typically $10–$30), heating element assemblies range $30–$120 depending on brand and kit, thermostats are $10–$40. Labor for a technician typically adds $100–$250 depending on your area. Total cost usually falls between $50 (for a simple DIY fuse swap) and $300+ for technician labor plus parts. Always confirm parts and pricing for your exact model before proceeding.
