Is it worth replacing heating element in dryer?
If your dryer's heating element burns out more than once within a year or two, the thermal fuse, which is supposed to protect it, is probably defective, so it's a good idea to replace it. The temperature in the heating chamber may also be too high, and that may be caused by poor venting.
What's wrong with a dryer when it doesn't get hot?
Common reasons for an electric or gas dryer not heating are a tripped circuit breaker, clogged vent, and no gas flow. Other potential reasons include a faulty thermal fuse and broken heating element. If you gather your tools and follow this guide, you may be able to solve basic dryer heating problems on your own.
Why is my dryer hot but not drying?
If your clothes dryer feels really hot, but your clothes take forever to dry, the vent may be clogged. A clogged vent traps the excess hot air inside the dryer's drum, but the low circulation of air keeps clothes from getting dry. Make sure you're always cleaning off the lint screen before you run the dryer.
What is the purpose of high limit?
During normal operation, the high limit switch's main job is to control when the blower fan turns on and off. The blower fan needs to be controlled by the limit switch rather than the thermostat. This is because you don't actually want the blower fan to turn on and off at the same time as the gas burner.
How does a high limit stat work?
Anytime you have an element that heats, safety dictates you have a way to stop the appliance from overheating in case the temperature-regulating controls fail. That's what the high-limit thermostat does: It shuts off the heating element if the water reaches an upper temperature limit, usually about 200 degrees.
Is a high limit thermostat the same as a thermal fuse?
The thermal cut-off (fuse) is meant to trip at a higher temperature than that of a high limit thermostat. This is a one time use fuse, so when it does trip, you must replace it. The hi-limit thermostat acts as a safety mechanism that keeps the dryer from overheating.
What causes dryer thermostat failure?

What is a thermostat?
A Thermostat is basically a temperature sensor with a switch and a memory (to set the desired temperature). Based on the set temperature, a thermostat switches the HVAC system (heating/cooling system of your home) “ ON ” or “ OFF ” to regulate the temperature inside the room in which the thermostat is installed.
How to classify thermostats?
As already discussed, we classify thermostats on two basis. 1) Based on Mode of Operation and 2) Based on Features & Functions. Based on mode of operation, we classify into Line Voltage Thermostat & Low Voltage Thermostat. Based on features we can see Smart Thermostats, Programmable Thermostats, Non Programmable Thermostats & Manual Thermostats. Let’s see how all these types differ from each other.
What is the difference between a mechanical thermostat and a non-programmable thermostat?
Non programmable electronic thermostats function similar to the mechanical thermostats; the major difference is the metal coil in the mechanical thermostat is replaced by an electric temperature sensor in this device . A tiny microprocessor that is set inside this thermostat sends ‘start’ or ‘stop’ commands to the heating or cooling system based on the reading it takes and the chosen temperature setting. In fact they are more accurate than the mechanical alternatives, but, you have to set the favorite temperature manually and make necessary changes during the course of the day manually.
How many volts does a thermostat run?
They typically run at 24 volts and they control blowers, fans and pumps (turning them ON/OFF) to regulate the temperature in different rooms. Remember a low voltage thermostat only control (switching) these parts like blowers/fans; thermostats do not power them.
Why are old fashioned thermostats called old fashioned thermostats?
These thermostats are generally referred to as old fashioned thermostats mainly because they are not programmable and they are not very efficient in regulating a room temperature like a digital thermostat. Besides being the oldest type of thermostat, many people still use it merely because these are quite simple to install and use and above all, very cheap. You can see this type of thermostat particularly in older houses.
What is non programmable thermostat?
Non programmable digital thermostats are other kind of thermostats that can be controlled with a digital display.
Why use a low voltage thermostat?
A low voltage programmable thermostat helps you to have the temperature in your house adjusted automatically according to preset times. This will help you conserve energy as you can allow the device to minimize the temperature when you are away from home and maximize the temperature when you are around.
Why do we need a thermostat for a dryer?
Repair Clinic says that a cycling thermostat cycles the heat on and off to maintain the proper temperature. The high limit monitors the dryer temperature and shuts off the heating element if the dryer overheats. There is also a difference between a thermostat and a thermistor.
How to tell if dryer thermostat is bad?
If the dryer does heat up, a bad dryer thermostat can result in loss of temperature control. If you have a faulty dryer thermostat, the dryer may keep the heat on for too long, causing the dryer to get too hot. If the cycling thermostat is defective, the dryer will not heat up.
What causes a gas dryer to not work?
