My dryer says "cooling" and

SOURCE: it wont dry my clothes

Check the following for a gas dryer--


1. Gas valve coils
Igniter glows, then shuts off without igniting gas - the problem is probably with defective coils (black, located on top of the gas valve). It is recommended to replace all coils (usually two or three) if found defective.

Note: Sometimes the whole gas valve may be defective, thus not letting the gas out. However, this problem is not common.

2. Thermal fuse
Most dryers have a thermal fuse, which burns out when the dryer overheats, in which case the dryer will either not run at all or stop heating. The fuse is usually located on the vent duct, inside the dryer. A blown fuse will show no continuity when measured with a meter. Before replacing the fuse, make sure the blower wheel is not broken or clogged, and there is nothing blocking the venting.

Note: It is recommended by most dryer manufacturers to replace a hi-limit thermostat when replacing a thermal fuse.

3. Igniter
Igniter may burn out or break. Replace the igniter if found defective.

Note: Igniters are very fragile and break easily. It is recommended to handle the igniter only touching the ceramic part of it (usually white in color).

4. Flame sensor (or radiant heat sensor)
Replace the sensor (located near the igniter) if found defective.


Check the following for a electric dryer--


1. No power to the dryer
Make sure there's power getting to the dryer. Check for tripped circuit breakers or blown fuses. An electric dryer uses two circuit breakers or fuses, and if only one of two is tripped or blown, the dryer might still run but not heat. Sometimes the power cord disconnects or burns at the dryer, if this is the case, the wiring and the terminal block must be repaired or replaced.

2. Heating element
A burned out heating element will show no continuity when measured with a meter. Replace the element if found defective.

3. Thermal fuse
Most dryers have a thermal fuse, which burns out when the dryer overheats, in which case the dryer will either not run at all or stop heating. The fuse is usually located on the vent duct, inside the dryer. A blown fuse will show no continuity when measured with a meter. Before replacing the fuse, make sure the blower wheel is not broken or clogged, and there is nothing blocking the venting.

If your dryer doesn't heat, check these:

Power from the house
Heating element
Thermal fuse
Wiring
Power from the house Check to see whether there's power getting to the dryer. Is it plugged in? Check for blown fuses or tripped circuit breakers--your dryer uses two fuses or circuit breakers. The dryer could tumble but not heat if only one of the two fuses is blown. If you have circuit breakers, one of the two circuit breakers can trip, even if the two for the dryer are connected.

Heating element Often a dryer heating element burns out, but doesn't trip the circuit breaker or blow a fuse. The heating element is simply a long coil of special wire. You can check it for continuity with an ohm meter. No continuity means the element is bad and you need to replace it--electric heating elements aren't repairable.

Thermal fuse On many dryers, there's a thermal fuse mounted to the exhaust duct inside the back cover panel. The fuse--which is about an inch long--is usually embedded in black resin and mounted in a white plastic housing. If the fuse has blown, you need to replace it. (You can't re-set it.)

Wiring A common problem is for the main wiring connection from the house, at the dryer, to burn and break its connection. Because the dryer can still tumble with partial power, the connection may be only partially defective. You may need to replace both the power cord to the dryer and the terminal block inside the dryer that the wire is attached to.

I had a similar problem years back. It was the ignitor. The ignitor is a ceramic like piece that heats up (glows red) that ignites the gas. Typically when that goes, you will see some white residue build up where it cracked, thus breaking the electrical connection. This thing works like a heating element on an electric stove, but rougher looking.

The part was about $30 at my local parts store. I bought an extra one just in case so I have it on hand. I installed it with common tools.

You can check it to see if you lost connection by using a volt meter.

Good luck.

Replace the gas coils on the gas valve.

I would supect a faulty high limit thermostat. This small round device is mounted to a metal plate and attached to the internal ductwork. It can be tested using a multimeter or ohmmeter. Test for continuity. It should have none. Hope this helped and best wishes.
