Oven Convection Fan Not Working? 6 Causes and What to Do
A convection fan that will not spin is usually a failed fan motor, a seized blade, a door switch or a relay on the control board. Here is how to narrow it down.
Read the guideWhy is my dryer overheating?
A dryer overheats when hot air cannot leave the drum fast enough or when a part stops controlling the heat. The most common cause is lint built up in the vent duct or a crushed vent hose behind the dryer. Other causes include a failed cycling thermostat, a stuck heater relay, a weak blower wheel, an overloaded drum, and a grounded heating element on an electric dryer.
If you need it checked soon, our appliance repair Mountain View CA techs fix gas and electric dryers from all major brands.
Signs of overheating include clothes that come out very hot, a top panel that is hot to the touch, a burning smell, and a dryer that stops early.
What should you do right now?
- Stop the cycle and unplug the dryer, or turn off its breaker.
- Take out the load and let the clothes cool on a flat surface.
- Do not run another load until you find the cause.
- If you see smoke or flame, leave the home and call 911.
The U.S. Fire Administration reports that failure to clean is a leading factor in home dryer fires. A hot dryer is worth taking seriously.
What are the 6 most common causes?
1. Clogged vent duct
Lint builds up in the duct over time, especially in long runs to a roof vent. Many Mountain View townhomes and condos have long or shared vent runs, and these clog faster.
2. Crushed or kinked vent hose
The foil hose behind the dryer is easy to crush when the dryer is pushed back. A flat spot chokes the airflow.
3. Full lint screen or lint in the housing
Clean the screen every load. Lint also slips past the screen into the housing below it.
4. Failed cycling thermostat
This part turns the heat off and on to hold the set temperature. When it sticks closed, the heat stays on.
5. Grounded or shorted heating element
On electric dryers, a damaged element can touch the housing and stay on even when the dryer is off. That is a serious safety problem.
6. Weak blower wheel or motor
The blower pushes air out the vent. A cracked wheel or a slow motor moves less air, so heat builds up.
How do you check the vent airflow?
Run the dryer on air-only or low heat and go outside to the vent hood. You should feel a strong, steady stream of warm air and see the flap open fully. Weak or no airflow means a blocked duct. Clean the lint screen, pull the dryer out, check the hose for kinks, and clean or replace the duct. Long roof runs are best cleaned by a pro.
Our guide to dryer vent cleaning and fire safety walks through this step by step. If the dryer takes forever after the vent is clean, read dryer takes too long to dry.

When should you call a technician?
Call if the vent is clear but the dryer still runs hot, if it keeps heating with the door open or the timer off, if you smell burning, or if the dryer shuts off early every cycle. These point to a thermostat, element, relay or blower problem. Most dryer repairs in Mountain View run about $150 to $400 with parts and labor.
A dryer that will not heat at all is a different problem. See dryer not heating. If your washer is also giving trouble, see our washer repair Mountain View page. A fridge that runs warm in the same laundry area can be checked on the refrigerator repair Mountain View page.

Frequently asked questions
Is an overheating dryer dangerous?
Yes. Heat plus lint is a fire risk. Stop using the dryer until the vent is clear and the cause is found.
Why does my dryer shut off after a few minutes?
A blocked vent makes the dryer hot, and a safety thermostat cuts the heat or the motor. Clear the vent first.
How much does dryer repair cost in Mountain View?
Most dryer repairs run about $150 to $400 with parts and labor. A thermostat or fuse is usually at the lower end. You get the price first.
