Understanding the Problem
The code or message 'HEA' on many dryers is commonly used to indicate a heater-related fault or a failure in the dryer’s heat circuit. If your RED4516FW0 (model as typed) displays HEA or the dryer tumbles but does not produce heat, the issue is almost always in the heating system or a safety device that prevents the heater from turning on. Typical components involved include the heating element (electric dryers), the thermal fuse or high-limit thermostat, cycling thermostat, control/relay on the main board, or (for gas dryers) the igniter and gas valve coils. Because exact naming and error codes vary by manufacturer, confirm whether HEA is an on-screen code or an observed symptom (no heat). If it's a no-heat condition with normal tumbling, start with the basic safety devices and then test the heating element or gas ignition path. Always disconnect power (and gas supply for gas dryers) before inspecting or testing components. If you’re unsure about the model identification (RED4516FW0), check the dryer’s rating plate — correct model ID helps when ordering parts or finding wiring diagrams.
Common Symptoms
Dryer tumbles but produces no heat; long dry times; error code or display reading 'HEA' (heater/heat fault); sometimes dryer will run intermittently or trips breaker when attempting to heat.
Common Causes
- Blown thermal fuse or open high-limit thermostat (safety devices interrupting the heater circuit)
- Failed heating element (electric dryers) or failed igniter/gas valve coils (gas dryers)
- Faulty control board, heat relay, or wiring/connection problems in the heat circuit

Helpful Repair Tip
Use a multimeter to check continuity: start with the thermal fuse (often located on the blower housing or exhaust duct) — if it’s open (no continuity) replace it. For electric dryers, test the heating element for continuity next. For gas dryers, test the igniter for continuity and watch for a glow when the dryer attempts to heat (with a second person starting the cycle).
Frequently Asked Questions
How do I know whether the thermal fuse or the heating element is bad?
Start with the thermal fuse because it’s a common, inexpensive failure that kills all heating. Unplug the dryer, locate the thermal fuse (usually on the blower housing or exhaust duct), remove it and test for continuity with a multimeter — no continuity means it’s blown and should be replaced. If the fuse has continuity, next remove and test the heating element for continuity. An open heating element or visible breaks/damaged coils means the element must be replaced.
Can I run the dryer without replacing the thermal fuse to get it working temporarily?
No — do not bypass or remove the thermal fuse. The thermal fuse is a critical safety device that prevents fires by shutting off heat if the dryer overheats. Bypassing it is dangerous, may cause a fire, and will void warranties and violate safety regulations. Replace any blown safety components with the correct replacement part for your model.
