Frigidaire Dryer Not Heating — Thermal Fuse, Heating Element & Thermostat Guide

Common Symptoms

• Dryer tumbles and runs full cycle but clothes come out cold and wet
• Dryer heats briefly then stops heating mid-cycle
• E64 error code displayed — heating element open circuit
• Gas dryer: drum turns, you can hear the igniter click but no flame lights
• Dryer takes multiple cycles to dry a normal load — marginal heat
• Thermal fuse location on heater housing shows burn or scorch marks
• Clothes are warm but still damp — cycling thermostat likely fault

Most Likely Causes

1. 1

   Thermal Limiter Fuse Blown (Part 3204267 — ~$8) — Most Common

   The thermal limiter fuse is a one-time-use safety device that permanently opens (blows) when the dryer exceeds a critical temperature threshold — typically around 309°F. Once blown, it cuts power to the entire heating circuit and the dryer produces no heat at all. Part 3204267 is the OEM thermal limiter fuse for most Frigidaire Affinity and Gallery dryers. It mounts directly on the heater housing or exhaust duct with one screw and two spade connectors. Testing: set your multimeter to continuity mode and probe the two fuse terminals — a good fuse shows continuity (beep, 0–2 Ω); a blown fuse shows OL (no continuity). A blown thermal fuse is almost always caused by a blocked exhaust vent. Always clean the full vent duct before replacing the fuse, or the new fuse will blow in the next few cycles.

2. 2

   Heating Element Failed (Part 5308EL8101A — ~$30) — Electric Dryers

   The heating element is a 240V resistance coil mounted in the heater box behind the drum on Frigidaire electric dryers. When the coil wire burns through, the circuit opens and no heat is produced — the dryer may display E64. Part 5308EL8101A is the OEM element for many Frigidaire Affinity electric dryers. Testing: disconnect power, remove the back panel, disconnect the element terminals, and probe with a multimeter in resistance mode. Expected resistance: 9–12 Ω across the element terminals at room temperature. A reading of OL (infinite resistance) confirms an open (broken) element. A reading near 0 Ω (shorted element) is also a failure. Note: a burned-through element often has visible damage at the coil — a melted or broken section of the resistance wire.

3. 3

   Gas Valve Coils or Igniter Failed — Gas Dryers

   On Frigidaire gas dryers, heat is generated by a gas burner ignition system rather than a resistance element. The two most common no-heat failures in gas dryers are: (1) Failed gas valve coils — the valve coils open the gas valve when energized by the igniter circuit; when they fail, the valve never opens, so gas doesn't flow and no flame lights. You may hear the igniter glow briefly and then click off with no flame. Testing the valve coils: each coil should read 1,200–1,500 Ω on a multimeter; a reading of OL indicates an open coil. (2) Failed igniter — the igniter glows orange-red to ignite the gas; over time the igniter element cracks or burns out. Testing: a good igniter reads 50–400 Ω; OL indicates failure. The igniter is visible through the burner observation port.

4. 4

   Cycling Thermostat Failed

   The cycling thermostat regulates the drum temperature by cycling the heating element (or gas burner) on and off throughout the drying cycle. It opens at the set temperature to turn off heat, then closes again as the drum cools to re-enable heat. When the cycling thermostat fails in the open position, it prevents the heating circuit from re-energizing after the initial heat-off phase, so the dryer tumbles warm at first but quickly cools to room temperature. Testing: set your multimeter to continuity mode and probe the thermostat terminals at room temperature — a good cycling thermostat shows continuity (closed) at room temperature and OL at its set-point temperature. Typical set-point for Frigidaire cycling thermostats: 135°F–155°F depending on the model.

5. 5

   Hi-Limit Thermostat Tripped or Failed

   The hi-limit thermostat is a backup safety thermostat mounted on the heater housing that opens the heating circuit if the dryer reaches an excessive temperature — typically 250°F–300°F. Unlike the thermal fuse, some hi-limit thermostats are auto-reset (they close again once the temperature drops) and some are manual-reset. A failed hi-limit thermostat that stays open will produce the same no-heat symptom as a blown thermal fuse. Testing at room temperature: a good hi-limit thermostat shows continuity (closed). An OL reading at room temperature indicates a failed (stuck open) thermostat. A repeatedly tripping hi-limit points to a vent restriction or a failed cycling thermostat that is allowing excessive temperatures.

Quick DIY Checks

1. 1Before any disassembly: confirm the dryer is truly not heating. Run the dryer on the highest heat setting for 5 minutes with a small load — open the door and feel the drum interior. Completely cold = total heating failure (thermal fuse or element). Mildly warm but not hot = marginal heating (cycling thermostat or thermistor). Also confirm the dryer is plugged into a 240V outlet and that BOTH legs of the circuit breaker are fully on — a partial breaker trip on a 240V circuit can power the motor (120V) but kill the heating element (requires both 120V legs = 240V total).
2. 2Test the thermal limiter fuse first — it is the most common failure and the cheapest part. Unplug the dryer. On most Frigidaire Affinity models, access the thermal fuse by removing the back panel (8–10 screws). The fuse (part 3204267) is a small oval component mounted on the heater housing or exhaust duct with two spade wire connectors. Pull off the spade connectors, set your multimeter to continuity mode, and probe the two fuse terminals. Result: beep / 0–2 Ω = good fuse. OL (no beep) = blown fuse, must replace. If the fuse is blown, clean the entire vent duct before installing the new fuse.
3. 3Test the heating element (electric dryers, part 5308EL8101A). With the back panel removed, the heater box is a rectangular metal housing — the element is visible as a coil inside. Disconnect both element terminals and probe with multimeter in resistance (Ω) mode. Expected: 9–12 Ω. OL = open element (replace). Also look for visible breaks or melted sections in the coil. While the element is exposed, also test the hi-limit thermostat (mounted on the heater box): continuity = good; OL at room temperature = failed.

1. 4Test the cycling thermostat. The cycling thermostat is typically mounted on the blower housing (not the heater box). Disconnect its two-wire connector and probe in continuity mode at room temperature — should show continuity (closed). OL at room temperature = failed open. If the cycling thermostat tests good but the dryer still produces marginal heat, test the thermistor as well (see /fixes/frigidaire-dryer-error-codes for E4A — thermistor should read 10,000–12,000 Ω at room temperature).
2. 5For gas dryers: test the igniter and gas valve coils. The igniter is visible through the small observation port in the burner housing — it should glow orange-red for 15–30 seconds and then the gas should ignite. If the igniter glows but no flame appears, the gas valve coils have failed. Disconnect power and probe each coil: expected 1,200–1,500 Ω each; OL = failed coil. If the igniter does not glow at all, probe the igniter terminals: 50–400 Ω = good; OL = failed igniter. Replace the failed component — igniter and coil sets are available as a kit.
3. 6Replace confirmed failed components. Thermal fuse (3204267): remove two screws, swap spade connectors. Heating element (5308EL8101A): slide old element out of heater box housing, note coil routing, install new element in same orientation. Cycling thermostat: two screws and a two-wire connector. Hi-limit thermostat: two screws and two spade connectors. Reconnect all wiring, reinstall panels, and run a full test cycle to confirm heat is restored.
4. 7After any heating repair, run an empty high-heat cycle for 15 minutes and verify: (1) the drum air is hot to the touch when the door is opened at the 5-minute mark; (2) warm air is exhausting from the exterior vent cap; (3) no error codes appear; (4) the full cycle completes normally. If heat is still absent or marginal after component replacement, the control board's relay may have failed — the board controls the heating circuit and a failed relay on the board prevents heat even with all heating components in good condition.
