Hi.

As first thing try replacing the thermal fuse.

The thermal fuse is located in the blower housing, near to the exhaust at the back of the dryer. The thermal fuse cost is only few dollars. Before replacement it can be tested reading Ohms with a multimeter. If the multimeter set on impedance reads infinite Ohms (No continuity, same as on air), then the fuse must be replaced. A good fuse must read low or zero impedance.

If the thermal fuse is OK, the next parts to test are the thermostats. On GE gas dryers there are at least two thermostats. One is a control of themperature, the other is an high limit. High limit is hosted on the blower housing, near to the thermal fuse. There is one or two thermostats near to the blower wheel. Often there is a safety thermostat near to the burner. To get details on the specific model check the schematics tucked inside the appliance or available online.
The thermostats are tested reading Ohms at room temperature. If any of them returns no continuity at room, then the thermostat is faulty and must be replaced.

If the thermostats and fuse are OK, then the next step is checking valve and igniter. The igniter or glowbar is tested energizing it and observing if there is spark. The valve is tested reading Ohms on solenoid with multimeter set at Rx1. If the solenoid has no continuity, then the valve is faulty. There is also a flame sensor that can be tested reading impedance or jumping its contacts.

If all the parts listed above are OK, then wiring and electronic timer control board must be tested reading voltages at contacts.

The problem is likely the thermal fuse or one of the thermostats.

Apart replacing the part, ensure that the hoses are not blocked , and that there is no lint inside the machine. This may have caused the fuse blowing.

Here a general diagram that can help you in identifying parts.

All tests must be done by a trained technician.

To get a technician on site , or to get a quote on repair ring the number listed on the owners manual.You can also get an US technician contact using our directory:Contacts.

To get parts ring GE at the number on manual.

You can also use one of the websites listed here to get parts and diagrams:

DLG5966G will not get hot. Vents have been cleaned and replaced with newer shorter ones. The heating mechanism sensor has been wiped clean...what could be causing it not to heat?


check if the igniter is glowing at all upon startup. you will need to partially disassemble dryer to check. if the igniter doesnt glow, then check the safety t-stat on flame tube body. it has a reset button on it. beyond that, it could be a gas valve problem, igniter itself; circuit board, etc..etc.

My Dryer spins but doesn't heat up. I checked both soides of the breaker and they are both working so the electricity is going to the dryer but it doesnt get hot. Where should I start ?


Hi,

If you are having problems with your gas dryer not heating the most common problem is that the ignitor goes bad. Even though it glows sometimes it is still not working properly.



if you dryer is gas check out this gas no heat tip....



If you have an electric dryer, you can have many different things that can go wrong causing the dryer not to heat.



check out this electric no heat tip...

Doesn't get very hot


The only thing that will fail later on in the cycle would be your gas coils. They come with the gas valve on all LG's. But if your getting heat all the way through the cycle then I would check your venting and make sure its not restricted. This will cause long dry times. Hope this helps. _MJ_

My dryer doesnt get hot


With gas bills so outrageously high these days, you deserve a medal for being able to keep current! lol Let's see what we can do about the dryer. First, check that the ignitor is working. It should glow an orange color if it is working. If the ignitor seems to be working properly, then I would suspect faulty gas valve coils. These are solenoids located directly above the gas valves, that when energized, open the valves and permit gas to flow to the burner. If the solenoids are faulty, the gas valves won't open and the burner cannot light. Due to the difficulty in testing these solenoids, it is best to replace both (all) of them at once if any are suspected of being faulty. Hope this helped and best wishes.
