GE Dryer overheating
Quick answer: Clothes come out scorching hot or shrunken, the top of the cabinet is too hot to touch, or the dryer shuts off with a burning smell.
- An overheating dryer is a fire hazard; stop using it until the cause is found.
- Let the dryer cool fully and unplug it before opening the heater housing.
- Never bypass a thermal fuse or high-limit thermostat that has opened; it did its job.
Why is my dryer getting too hot?
Clothes come out scorching hot or shrunken, the top of the cabinet is too hot to touch, or the dryer shuts off with a burning smell. The cause is almost always restricted airflow from a clogged exhaust vent, lint-packed blower or dirty lint screen, which traps heat that should be leaving with the exhaust. If airflow is good, a cycling thermostat stuck closed, a heating element shorted to ground so it stays on even when the thermostat opens, or a gas valve that will not close is letting the heater run without control.

Most Likely Causes, in Order
1. Restricted airflow from a clogged vent or blower
The heater is sized to warm a steady stream of air. When lint blocks the vent, screen housing or blower wheel, the same heat goes into far less air and the drum temperature climbs until a thermostat or fuse cuts it.
How to check: Run the dryer and feel the airflow at the outside vent hood; it should be strong enough to lift the flap fully. Disconnect the duct at the dryer and compare airflow straight from the outlet; if it is much stronger there, the duct is blocked. Unplug the dryer and inspect the lint housing and blower wheel for packed lint.
Fix: Clean the entire duct run and outside hood, clear the blower housing, wash the lint screen, and replace flexible foil hose with rigid metal duct. (Difficulty: Easy)

2. Cycling thermostat stuck closed
The cycling thermostat is supposed to open and cut heat when exhaust air reaches its set point. If its contacts weld closed, the heater never cycles off and only the high-limit thermostat or thermal cutoff stands between the dryer and a fire.
How to check: With airflow confirmed good, run the dryer on high with a thermometer probe in the exhaust duct and watch whether the heat clicks off near the set point of roughly 130 to 160 degrees Fahrenheit. If the temperature keeps climbing past that with no cycling, the thermostat is stuck. A bench test with a heat gun on the removed thermostat should show it open and lose continuity as it warms.
Fix: Replace the cycling thermostat, and replace the high-limit thermostat and thermal cutoff as well if they have been repeatedly stressed. (Difficulty: Easy)

3. Heating element shorted to ground (electric)
If a sagging element coil touches the metal housing, current can flow through the housing to ground and bypass the thermostats. The element then stays hot even when the controls turn it off, and sometimes even after the cycle ends.
How to check: Unplug the dryer, remove the wires from the element and test with a multimeter from each terminal to the heater housing metal. Any continuity at all, even a high reading, means the coil is grounded. Look inside the housing for a coil sagging out of its insulators or discolored spots.
Fix: Replace the element or heater housing assembly. Because the short bypasses the safeties, replace the thermal cutoff and high-limit thermostat at the same time. (Difficulty: Moderate)

4. Gas valve not closing (gas)
A gas valve with a stuck plunger or debris in the seat keeps feeding the burner after the cycling thermostat opens, so the flame never shuts off and the drum overheats.
How to check: Remove the lower front panel and watch the burner during a cycle from a safe distance. The flame should shut off every few minutes when the thermostat opens and relight when it closes. A flame that burns continuously with good airflow, or that stays lit after the dryer is turned off, means the valve is not closing.
Fix: Shut the gas supply immediately and have the gas valve assembly replaced by a qualified technician. (Difficulty: Advanced)

5. Failed high-limit thermostat or relay on control board
On electronic dryers a heater relay on the control board switches the element. A relay welded closed keeps the heater on regardless of the thermistor reading, and a high-limit thermostat that has been stressed too many times may no longer open when it should.
How to check: Rule out airflow, the cycling thermostat and a grounded element first. Then unplug the dryer and test the thermistor on the blower housing for the resistance listed on the tech sheet at room temperature; a thermistor that reads far off makes the board think the air is cold. If the thermistor is fine and the heater still will not cycle off, the board relay is the likely fault.
Fix: Replace the thermistor if it reads out of range, otherwise replace the main control board. (Difficulty: Moderate)

Frequently Asked Questions
Why does my dryer keep blowing the thermal fuse?
The fuse opens when exhaust temperature exceeds its rating, so repeat failures mean the dryer is still overheating. Clean the whole vent run and blower, then check the cycling thermostat and test the element for a short to ground before installing another fuse.
Is it normal for the top of the dryer to be hot?
Warm is normal; too hot to rest a hand on is not. Excess cabinet heat means hot air is not leaving through the vent, so check the exhaust path first.
Can overheating damage my clothes?
Yes. Excess heat shrinks cotton, sets wrinkles, melts elastic and can scorch fabric left in contact with the drum. Use the dryer on air fluff only until the overheating is fixed.
When to Call a Professional
Call a technician immediately if you see a burner flame that will not shut off, smell gas or burning insulation, find scorch marks inside the cabinet, or the thermal fuse blows again after the vent has been cleaned and the thermostats replaced.
