What does Frigidaire Dryer Won't Stop - Causes & Fix mean?

A stuck heater relay on the control board keeps the dryer running or heating. Reset power, check venting, then replace the board.

How do I fix Frigidaire Dryer Won't Stop - Causes & Fix?

Work through the step-by-step fix below. Start with the quick reset and the most common cause, then check the specific part this guide points to. Most fixes need only basic hand tools and the right replacement part.

Can I keep using my Frigidaire appliance with this error showing?

Usually not. Frigidaire appliances show this error when a part or safety circuit is out of range, so running it can stop the cycle or make the problem worse. Diagnose and clear the error before normal use.

What part is most commonly replaced for Frigidaire Dryer Won't Stop - Causes & Fix?

The parts that most often fix Frigidaire Dryer Won't Stop - Causes & Fix are listed in the parts section of this guide. Match the part to your exact model and serial number before you buy.

Is Frigidaire Dryer Won't Stop - Causes & Fix a DIY repair or do I need a technician?

Many fixes are DIY-friendly with basic tools, such as door switches, drain pumps, water inlet valves, thermostats, heating elements, and filters. Sealed-system, refrigerant, gas, or high-voltage work should go to a licensed technician for safety.

Frigidaire Dryer Won't Stop - Causes & Fix

Frigidaire Dryer Won’t Stop — What’s Happening

When a Frigidaire dryer won’t stop running or heating, it usually means a relay on the electronic control board is stuck closed, keeping power to the heater element even after the cycle should end. This symptom often appears alongside code E8C, which signals frequent high-limit thermostat trips due to overheating. The dryer may continue to tumble and heat indefinitely, or it may cycle on and off repeatedly without responding to the timer.

Less often, a door switch problem or a failed high-limit thermostat can prevent the dryer from recognizing when to stop. If the dryer also displays a DR code or won’t start at all, the door switch or latch may be the root cause. In most cases, though, a runaway dryer points to either a clogged exhaust vent causing overheating or a control board relay that has welded itself shut.

Most Likely Causes

Stuck heater relay on the electronic control board The relay contacts weld closed and keep sending power to the heating element, so the dryer continues to heat even after the cycle timer expires.
Restricted exhaust vent or lint blockage Clogged venting forces the high-limit thermostat to trip repeatedly, which can trigger E8C and cause the dryer to overheat or run longer than normal.
Faulty electronic control board A board that cannot process signals correctly may fail to end the cycle or respond to the timer, especially if a power reset does not clear the fault.
Bad door switch If the switch fails to signal that the door is closed, the dryer may not start or may run erratically, and you may see a DR code on the display.
Failed thermistor or high-limit thermostat A thermistor reading far from the expected 50,000 ohms or an open high-limit device can prevent the control board from monitoring temperature correctly, leading to runaway heating.

How to Diagnose and Fix

Unplug the dryer for five to ten minutes to reset the electronic control board, then restore power and run a test cycle to see if the fault clears.
Pull out the lint filter and vacuum the filter housing, then disconnect the exhaust duct from the back of the dryer and check both the duct and the outdoor vent cap for lint buildup or blockage.
Note any error code on the display; E8C indicates frequent high-limit trips due to overheating, while DR points to a door-switch or door-latch issue.
If you suspect a door problem, unplug the dryer, locate the door switch behind the front panel or door strike, and use a multimeter to measure continuity from COM to NO with the door closed; a good switch reads near 0.1 ohms, and an open or OL reading means the switch is bad.
If the model uses a thermistor for temperature sensing, disconnect power, locate the thermistor on the blower housing or heater assembly, and measure its resistance; it should read around 50,000 ohms at room temperature.
Inspect the electronic control board for signs of a stuck relay, burned traces, or visible damage; if the dryer still won’t stop after reset and venting checks, the board is the most likely culprit.
Replace the door switch if it fails continuity testing, clean or repair the exhaust system if airflow is restricted, or install a new electronic control board if the relay is stuck or the fault persists.

Parts You Might Need

Part	Notes
Electronic control board	Amazon \| Order by your dryer’s full model number; stuck relays are the most common cause of a dryer that won’t stop heating.
Door switch	Amazon \| Measure continuity with the door closed; replace if you read open or OL instead of near 0.1 ohms.
Thermistor	Amazon \| Should read approximately 50,000 ohms at room temperature; replace if resistance is far out of range or open.

If your appliance also shows a code on the display, these match this problem:

When to Call a Pro

Call a technician if you are not comfortable working inside the dryer cabinet or testing live control-board voltages. A pro can quickly isolate whether the fault is a stuck relay, a failed sensor, or a wiring issue, and many control boards require careful connector work that is easy to damage during a first-time repair. If the dryer has already tripped your household breaker or shows burn marks on the board, have a qualified technician inspect the unit before restoring power.
