Question about Whirlpool LGR4634J Gas Dryer

Whirl pool Dryer not staying hot

Recently, my dryer started to act up. What it is doing is this: When you first turn it on, it heats up and you can see the flame. This only lasts about a minute or two and then goes out and you get no heat. If you shut it off and wait, turn it back on you get the same results. If you turn it on right away, it doesn't even try to heat up. I have taken the back off and cleaned everything. I have ran it with out the vent hooked up. The second thing it is doing(may have been doing this for awhile without us noticing) is that on one setting, the timer does not move and the dryer will run and run....never getting hot. I have the sames exact problem, I have a LGR3624JQ0 Gas Dryer. Let me know if the solution works for you.

Ok, if the timer is malfunctioning, i recommend replacing this device asap. this can be the central issue. the timer is the brain and, if it is not functioning at optimal range, it will effect all components and the way they operate. replace th timer asap.

I would also check the following to address the heating issue as well but, im sure the fualty timer is the cuase.


Check the following before replacing the time just to be sure.

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.

My whirl pool dryer has to be turned on bout 3 to 4 times


Ok, check the exhaust hose for obstructions. make sure the blower assembly is not clogged and, the hose is clear of any debris. the exhaust hose should blow out hot air forcefully. if the force of the air isn't blowing hard, it will not create a suitable drying environment for the element. this poor ventilation will also damage the heating element or burner Assembly.

Now, if there is sufficient air flow out of the exhaust hose, this will confirm control failure. replace the dryness sensor and control board in this case.

Here's a quick way to test for clogs. take the hose of the backside of the dryer then, start the cycle. if the drum sorts to become hot after a few minutes with the exhaust hose removed form the back of the unit, this will confirm a major block in the hose or blower assembly.
