Question about Whirlpool LGR7646E Dryer

1 Answer

Whirlpool LGR7646EQ0 turns no heat

I can not find how to get the pilot light re-lit. And I don't know if it is the burner, or the ignitor that has gone bad. I have stuck a flame all around and nothing ignites, or lights.

Thank you!

    I have already checked the vent (from the lint trap to outside, and it is aok. I will check the power on the ignitor, and get back to you.

    Same problem here. Where do I get to ignitor? Took off the back but now sure where to go from here

    Same problem as well. Now taking the dryer apart to find the ignitor. I have the back panel off and will soon be taking more of the dryer apart. I'll let you know if I find it!

    I also have the same problem. Does anybody know if changing the thermal fuse (plastic part with two blue wires attached) is a troubleshooting option?

The dryer has no pilot light, haven't had them in years. It operates off a hot surface ignitor.I would check to see if you are getting power to the ignitor 115v. If you are the ignitor is bad. Sometimes you can see the ignitor cracked. Did it take long to dry the clothes before it quit? If so your vent may be clogged which will blow a thermal limit on the dryer and keep it from heating. hope this helps...

Burner lights and goes out


It may may be the safety system for pilot light is maladjusted. There is a sensor which has to be heated by the pilot light or the valve shuts down altogether. If the pilot light stays lit then you check to see if it is positioned to light main burner.

I have a Whirlpool gas dryer, I can see through the hole that the piolet light is not lit. Model #LGR7646EQ3. It is not heating to dry clothes, can I just try & relight the pilot light?


Hi, If you are having problems with your gas dryer not heatingthe most common problem is that the ignitor goes bad. Even though it glowssometimes 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 differentthings that can go wrong causing the dryer not to heat. check outthis electric no heat tip...

I have an old Kenmore 70 Series dryer, just this weekend, the drum turns but no heat..... after a little search online, I suspect the pilot light went out. Where is the pilot light located? I lost the...


The burner is on the lower right side of the bottom under the drum. See this manual pdf page 23 for location and access. https://secured.whirlpool.com/Service/SrvTechAdm.nsf/2cd44500d572193285256a45004fd9d6/4829abde74a34d7f85256ab000620794/$FILE/4322260.pdf

The burner uses an ignitor and a flame sensor vs a pilot light. See this link pages 12 - 14
https://secured.whirlpool.com/Service/SrvTechAdm.nsf/2cd44500d572193285256a45004fd9d6/c5c81d2c8f26b1b5852574f20055c20c/$FILE/4314010.pdf Note the M series burner has been in use since 1984.

The dryer must have a complete termperature circuit and no "high temp limit" failures for the ignitor to light. That means the door is closed, motor is running, and the cycle thermostat is less than 135 deg F and the High limit thermostat is less than 180 deg F just to provide power to the gas valve solenoids, ignitor, and radiant / flame sensor.

Drum turns but no Heat problem!!


Brian, if the glow ignitor comes on for a minute clicks and goes off then you need valve coils. if no glow at all could be ignitor or thermal fuse.

Not heating up Gas Dryer


Modern gas dryers do not have a pilot light. They have an electronic ignitor (glow or spark). A glow ignitor turns on several seconds before the gas turns on and should get orange hot. A spark ignitor should make a clicking or buzzing noise.

Most likely the ignitor is bad but you can check it fairly easily to make certain. The best instructions I have found are at

http://www.acmehowto.com/howto/appliance/dryer/gdryer/check/ignitor.php

If it is the ignitor it can be replaced with a few hand tools. Remove the bad ignitor. Write down the make, model, and serial # of your dryer. Call your local appliance parts store to see if they have one it stock before driving over there.

Have a Whirlpool Gas Dryer - model # lgr7646a spins but no heat


Thre is no pilot light. This dryer uses an ignitor (glow bar or coil).
Open the lower front "door" (small access door) and turn on dryer.
If the ignitor does not glow (bright orange), then the ignitor needs to be replaced ($60).
If it does glow, then the gas valve needs replacement ($60).
If it isd the valve, the internal spring is stuck. Do not try to repair it, you must replace it.

Intermittant flame, ignitor function is good, all other functions are as designed,timer ,tumble etc.


Hi

The pilot light flame would sometimes get very small and keep going out. This was usually because the pilot orifice was getting dirty and was partly plugged. The pilot orifice must be cleaned out when the flame becomes too small to light the main burner. You can blow air through the pilot assembly to help clean it out, don't use something metal in the pilot orifice hole or you risk enlarging the pilot gas feed hole and the pilot light may be too BIG. If your pilot flame keeps "going out", chances are you will need to replace the pilot latch do make sure the vent hood flapper is closing ok and no outside air blowing in is effecting the pilot flame.
This is a thermocouple that sensed the heat from the pilot flame and kept a small amount of gas flowing to allow the pilot light to stay lit. If you followed the instructions ( usually found inside the small access door on the front bottom ) on how to re-lite your pilot when it goes out and the flame will not stay on, replace the pilot latch assembly.

Please accept the solution and revert for further assistance.

Thanks

Where can I light the pilot


You're dryer has an ignitor not a pilot. To check, either pull the lower front panel or pop out the key hole. Start dryer and watch if the ignitor comes on it should shine brightly almost white. If it does'nt light at all(should at least turn red). there could be no voltage to the ignitor.

How do you light gas pilot light?


I don't think that there is a constant burning pilot light!! It should be automatic:
There is a ceramic ignitor that heats up red -hot, an electric eye sees the heat and turns on the gas valve ( on my Whirlpool).
