Frigidaire Dryer Not Heating: Thermal Fuse, Element & Thermostat Fixes
Quick answer
A Frigidaire dryer that tumbles but produces no heat almost always has a blown thermal fuse — a one-time safety device on the exhaust duct that permanently opens when the dryer overheats, most often from a clogged or kinked vent duct. Test the fuse with a multimeter across its two terminals: no continuity confirms failure. Replace the fuse AND clean the entire dryer vent duct before running another cycle — a blocked duct will blow the new fuse again.
Frigidaire dryers — including Frigidaire, Frigidaire Gallery, and Frigidaire Professional models — are widely installed in Northern Virginia townhomes, condos, and rental properties because of their reliability and affordability. When a Frigidaire dryer tumbles normally but produces no heat, or heats briefly and stops, the cause is in the heating circuit: thermal fuse, heating element (electric), gas igniter system (gas), or thermostats. The drum motor circuit is independent of the heating circuit, which is why the drum keeps spinning even when the heat side has completely failed.
Step 1 — Thermal Fuse (Most Common Cause, Both Electric and Gas)
The thermal fuse is the most common cause of a Frigidaire dryer not heating. It is a small, oval or rectangular one-time safety device mounted on the exhaust duct inside the dryer cabinet — on most Frigidaire electric models it is accessible from the back panel (6–8 screws); on gas models it is on the burner housing or exhaust duct near the burner assembly. When exhaust temperature exceeds the fuse's rated limit — almost always from a clogged lint screen, blocked vent duct, or kinked exhaust hose — the fuse permanently opens. Result: zero heat, drum still tumbles. To test: unplug the dryer, remove the back panel, locate the fuse on the exhaust duct (usually a small white or orange component with two push-on wire terminals), and test across the terminals with a multimeter on the continuity or resistance setting. A good fuse reads near zero ohms; an open circuit (OL, no reading, or infinite resistance) means it has failed. Frigidaire thermal fuses run $8–$20 in parts. Critical: before installing the new fuse, clean the full dryer vent duct from the dryer exhaust outlet to the exterior wall cap. A blocked duct is the root cause of the majority of Frigidaire thermal fuse failures — skip this step and the new fuse fails again, sometimes within days.
Step 2 — Heating Element (Electric Models)
On Frigidaire electric dryers, if the thermal fuse tests good but there is still no heat, the heating element is the next component to test. The element is a coiled nichrome resistance wire inside a metal cylindrical housing, typically mounted at the rear of the drum or in a heating chamber at the back of the cabinet. A broken element coil causes complete heat loss; a partially shorted coil may cause overheating and eventually blow the thermal fuse or high-limit thermostat. To test: unplug the dryer, remove the back panel, disconnect the element wire harness, and measure resistance across the two element terminals with a multimeter. A working Frigidaire heating element reads 8–20 ohms; an open circuit (OL or no reading) confirms the coil has broken. Inspect the element housing for burn marks or arcing, which can indicate an underlying cause of the failure. Frigidaire heating element assemblies run $25–$65 depending on model.
Step 3 — Gas Igniter, Radiant Sensor, and Gas Valve Coils (Gas Models)
On Frigidaire gas dryers, no heat almost always comes down to a failed igniter, failed radiant (flame) sensor, or failed gas valve coil set. The igniter must reach ignition temperature to open the gas valve through the heat-sensitive radiant sensor. A failed igniter: the igniter either does not glow, or glows weakly without reaching ignition temperature. Test with a multimeter — a good Frigidaire igniter reads 50–600 ohms; open circuit means failure ($15–$40 to replace). A failed radiant sensor: the igniter glows fully orange but the gas valve never opens. Replace the radiant sensor ($10–$25) and retest. Failed gas valve coils: the igniter and sensor work, but the solenoid coils are not actuating the valve. Test each coil — healthy coils read 1,000–1,500 ohms; shorted or open coils need replacement ($20–$50 for the coil kit). The burner assembly is accessible from the front lower panel on most Frigidaire front-load gas dryer models.
Step 4 — Cycling Thermostat and High-Limit Thermostat
Frigidaire dryers use two thermostats in the heating circuit. The cycling thermostat mounts on the exhaust duct and cycles the heating element or gas valve on and off to maintain the correct drum temperature. The high-limit thermostat is a secondary safety cutout on the element housing or exhaust duct. A cycling thermostat stuck open causes no heat or intermittent heat; stuck closed causes continuous overheating, which blows the thermal fuse. The high-limit thermostat stuck open also causes no heat. Test both at room temperature with a multimeter — both should show continuity (near zero ohms). Frigidaire thermostats run $10–$25 each. Key diagnostic clue: if a Frigidaire dryer has blown its thermal fuse more than once, the cycling thermostat is almost always the root cause — test it before replacing another fuse.
Step 5 — Moisture Sensor and Control Board
Frigidaire dryers use two metal sensor bars inside the drum — typically near the lint filter — to detect residual moisture and end the auto-dry cycle at the correct time. Fabric softener sheet residue coats the bars and causes the dryer to end the cycle too early, leaving clothes damp. Clean the sensor bars with rubbing alcohol and a clean cloth until the metal is bare. If the dryer produces no heat at all (not just ending early), sensor fouling is not the cause — this is purely a no-heat failure pattern. A control board fault — where the board does not send voltage to the heating circuit despite all heating components testing good — is rare on Frigidaire dryers and is a last-resort diagnosis. Measure voltage at the heating element terminals during a heat cycle before ordering a board. Frigidaire control boards run $80–$200 in parts.
When to Call a Specialist
Thermal fuse replacement and dryer vent cleaning are homeowner-accessible repairs on most Frigidaire models. Gas dryer igniter, radiant sensor, and gas valve coil replacement involve working near gas components — if you are not comfortable with gas appliances, a technician completes the repair safely and quickly. Heating element replacement on some Frigidaire front-load electric models requires significant cabinet disassembly; a technician avoids damaging the drum seals or belt in the process. If a Frigidaire dryer has blown its thermal fuse more than once, there is an underlying vent restriction or cycling thermostat fault that must be diagnosed before the next replacement — this is a technician-level root-cause diagnosis.

Frequently Asked Questions
Why does my Frigidaire dryer run but not heat?
The most common cause is a blown thermal fuse — a one-time safety device on the exhaust duct that permanently opens when the dryer overheats, most often from a clogged vent duct. The drum keeps tumbling because the motor circuit is separate from the heating circuit. Test the thermal fuse with a multimeter across its two terminals (no continuity = blown). Replace the fuse AND clean the entire dryer vent duct from the dryer outlet to the exterior cap. If the fuse has blown before, test the cycling thermostat — it is the most common root cause of repeat thermal fuse failures.
Can I reset a Frigidaire dryer that stopped heating?
There is no reset button for the heating circuit on most Frigidaire dryers — the thermal fuse is a one-time device that must be replaced, not reset. However, unplugging the dryer for 60 seconds may clear a control board error that interrupted a cycle. Also check the circuit breaker: 240V electric dryers need both legs of a split circuit, and losing one leg produces a dryer that tumbles with no heat. If the breaker is on and the thermal fuse tests good, the fault is in the heating element (electric) or igniter/radiant sensor system (gas).
