A faulty door switch, blown
Various things will cause a dryer not to start, including a blown thermal fuse, clogged vent, malfunctioning motor or control board, misaligned drum or rollers, engaged child lock, overloaded unit, broken or worn-out belt, broken start switch, defective door latch, tripped circuit breaker, faulty outlet, or an ...
Dryer motor issues
If your dryer's motor is overheating, it can trigger the thermal overload switch, shutting down the machine to help prevent fire hazards.
As a safety device, a dryer usually has a door switch that activates the working parts. Unless the door is properly closed, the dryer won't work, regardless of the settings on the control panel. Many dryers are equipped with a reset button on the control panel.
The high-limit thermostat, or thermal fuse, is a safety feature that's designed to trip whenever the dryer reaches a dangerous temperature. Once the thermal fuse reaches its threshold, it will turn off the heating element or dryer.
If your dryer is broken, call a local dryer repair company to fix it. Hiring a local dryer repair pro offers several advantages: They're experts on dryer operation. They know how to stay safe while working with gas or electricity.
Clothes dryers typically last for about 10 to 13 years. If your dryer has been around for nearly a decade, you will likely be searching for a replacement soon. Ancient dryers should get the boot, as older machines can actually cost you more money. Newer, certified models use less energy, helping you save on costs.
One of the prime culprits is the mains filter, also called the interference suppressor. This is designed to prevent the machine's motor from interfering with other electrical components. These can bulge or short out from moisture, particularly if the dryer is fitted in a damp utility room or similar.
As your dryer motor ages, wear and tear can cause it to get hotter during a cycle. Sometimes, all that extra heat can activate the thermal overload switch, which prevents a potential fire hazard and shuts off the machine. The motor may restart a few minutes later, once it's cooled down, but the problem won't disappear.
Dryer Shuts Off Quickly
Common issues include a broken motor relay, a malfunctioning push-to-start switch or timer, or a clogged exhaust vent that results in overheating. A malfunctioning electrical circuit board, a weakened door catch, or a broken door strike can be the cause.
There are several reasons why your dryer may not be drying, including a clogged lint screen, issues with the vent hose or a clogged vent system. Properly installing and maintaining your dryer can help avoid some issues that can interfere with performance.
How Do You Know if the Dryer is Too Hot? The tell-tale sign that your dryer is too hot is damage to your clothes. If you pull your clothes out of the dryer and notice that there are burn marks on them, your dryer is running far too hot. If your dryer is hot to the touch, that may be another sign of too much heat.
A dryer can catch fire while it's not running if there are any problems in the dryer's electrical system. This may result in wires and components sparking when the unit has been shut down. Over time, lint buildup may cause heat sensors to get too hot, which could lead them to ignite the material.
A blown thermal fuse often prevents an electric dryer from starting. You'll find the thermal fuse on the blower housing. Unplug the dryer and check the thermal fuse for continuity. Replace the thermal fuse if the multimeter measures no continuity.
The cost to replace a thermal fuse on a dryer is $75 to $150 on average. The cost of a dryer thermal fuse is $5 to $10 for the part or up to $60 for OEM parts. This safety device stops the motor when the dryer overheats. No one can repair or reset a thermal fuse.
Depending on your dryer model, you may find the thermostat in different areas, such as near the heating element or the blower fan housing. Once you find it, remove the cover, and use a multimeter to test the thermostat for continuity. If the reading shows an open circuit, then the thermostat needs replacement.
Check to make sure a household fuse has not blown or that a circuit breaker has tripped. Electric dryers use two household fuses or circuit breakers. Make sure both fuses are intact and tight, reset the circuit breaker, or replace the fuse if necessary. If the problem continues, call an electrician.
Dryer repair costs will vary depending on the issue. For example, it will cost much less to replace a dryer belt than a motor. That said, if your clothes dryer is more than halfway through its lifespan—7 years or more—and the repair costs more than 50% of the price of a new one, you should consider replacing it.
Your machine might've automatically switched off due to overheating or a full reservoir (in the case of condensing dryers). Check to see if you can turn the drum by hand. If you can, the belt might have snapped. The drum or motor might have seized if it's stuck or doesn't spin easily.
