    this is a gas unit so i dont think the voltage applies to this problem. were is the thermal cut-out (TCO) located and how can i test it.

  • edjaure May 29, 2009

    i checked the white fuse and it looks ok, if it was bad would it visibly look bad? the ignitor is not glowing at all. how can i test the flame sensor on the burner housing?

  • edjaure May 29, 2009

    turns out it is the fuse. i connected the two wires that go to the sensor and after a little while the heat came on. thanks!!

HI, Remove the little cap in the front lower left corner and start the dryer. Look to see if the ignitor comes on and watch to see if the ignitor shuts off before the flame comes on. If the ignitor works but no flame, you will need to change the coils on top the gas valve.
If there is no ignitor glowing at all, you will need to check the fuse on the back of the dryer located on the blower housing. If this is the sensor you checked and it is ok, then you will need to remove the front panel and check the flame sensor on the burner housing.
Please let me know if this has helped at all or if I can assist you further.

    To test the fuse you will need a voltage/ohms meter. Check the continuity on the fuse. If the circuit shows open, the fuse is bad.
    I hope this helps.
    If the fuse is bad, when you start the dryer, you should here a loud click from the gas valve. If there is no loud click, it is probably the fuse.

    no it will not visibly look bad.

    If you do not have a meter, UNPLUG the dryer and you can tape the wires together and then plug the dryer back in and se if the heat comes on. Try this first please. it is most common. If it doesn't start heat, I can walk you through testing sensor

    You are very welcome. Make sure that you change the fuse asap because it is a safety device. Make sure you venting to the outside is well cleaned out because that is sometimes the cause of the fuse going bad.

    Glad I could help you

The following link explains how to troubleshoot a dryer no heat problem:

http://www.fixya.com/support/r630242-dryer_runs_but_not_heat

The first step in troubleshooting this problem would be to check the voltage at the terminal block in the back of the dryer. This is where the power cord is installed. If you are missing one leg of the 220 service, the dryer will exhibit the same symptoms you describe. It will still run, because the drive motor only uses 110-120VAC, while the heating circuits require the full 220-240VAC service. You will need to check across the two hot leads (RED and BLACK wires) for a AC voltage reading of 220-240. CAUTION: There is live voltage present at the terminal block even with the dryer turned off. For your safety please unplug the dryer first and remove the cover plate on the terminal block. Then, plug the dryer back in to take your voltage measurement. Taking the reading this way will also confirm whether or not the power cord is good. If the voltage is good at the terminal block, the problem is INSIDE the dryer. If the voltage is incorrect, check the wall receptacle and/or breaker panel. If the power is good at the receptacle and bad at the terminal block, you have a bad power cord.

Pay particular attention to the section that discusses proper ventilation. Most dryer heat related problems are attributed to clogged, poorly installed, or kinked ventilation ducting. If you haven't checked your ventilation any time recently, now would be a good time to do so. In addition, it is highly recommended that you use the semi-rigid metal type ducting material. It resists crushing, kinking and is fire resistant. It also keeps rodents from chewing through it and building nests inside the dryer exhaust vent and blower housing (mice love lint). The reason I stress this so much, is because if you replace any failed components without verifying the ventilation is clear and clean, those same components will fail again. Not to mention, a clogged dryer is a fire hazard.

The most common failed component is the thermal cut-out (TCO). It is designed to trip like a fuse when the dryer heating circuits overheat. Once it trips, it has to be replaced. If this is the case, make sure you replace the high limit thermostat at the same time. These components work in conjunction and are often sold as a set. If you do not replace both parts, you run the risk of premature failure of any component you do replace. Both of these components are mounted on the heater box. The Hi-limit Thermostat is usually mounted adjacent to the ceramic leads of the heating element, while the TCO is mounted at the opposite end of the heater box. You will need to read through the link provided and check all components of the heating circuit to make sure, however. If you have questions, please let me know. I hope this is helpful to you.

    Gas or Electric does make a difference in how to troubleshoot these dryers. That would have been helpful to know in your intial question. I'm not going to steal the thunder of Maytag317. Please follow the advice of this expert for troubleshooting a gas dryer problem. The majority of gas dryer heat problems are caused by failed ignition. Check the burner assembly first, as Maytag317 advises.

Yeah the sensor that you cleaned have nothing to do with your heat that is for your sensor dry it sends a signal to your computer telling it that the clothes are still wet. sounds like either your breaker tripped on one side and you only have 120 volts when you should have 240 volts so check the simple stuff first. or you have a bad heating element. Do you feel any heat? sometimes if your exsaust is blocked this can cause a drying problem and you may think it has no heat but it does. Do you have a kick panel? at the bottom of the dryer

This is an air flow issue. Take the hose off the back of the dryer and run it and see if the error goes away. If it does not, something is plugging the inside of the dryer airflow.

Dryer Model LER3624JQ0 tumbles clothes, has heat, but clothes are hot and damp. Cleaned lint filter & took of vent in back (thought maybe clogged wall vent) but didn't help. Don't think much (if any)...


Hi,

If your dryer is not drying like it once did or if you just have nottaken the time to give yourself a clean dryer in a long time then youneed to do that. At least once a year the dryer cleaning should takeplace. Lint build up in the dryer duct is one of the main causesfor your dryer to fail.

I have a Whirlpool LGN2000PW gas dryer. The dryer will heat up when it is first started and get warm, but after a few minutes it cools right back down. We removed all the duct work in the basement leading...


if it still quits heating after a minute or so then its either a weak cycling thermostat or moisture sensor thermistor,both located on the blower housing, or the moisture sensor bars located near the door opening on the dryer,or it could be a high limit thermostat thats bad on the burner tube itself

Whirlpool dryer model #GEW9250PT1 not drying properly


when was the last time you cleaned your dryer?all a dryer does is move air around and if it can't cycle through the dryer the clothes won't dry. unplug the dryer and then you need to clean the duct that the lint filter slides into,vac out the inside of dryer where the motor is and clean out the vent line,if the vent line is a long run from the back of dryer to the outside vent i use a leaf blower to clean it out,make sure the outside vent is clear first then blow it out,if it's a short run vac it out,most problems start just from lint buildup,the clothes don't dry the dryer runs hot and parts start messin up,also vac out under your fridge,take the bottom kick plate off and vac it out,you can kill the compreesor if you don't,good luck

Slow to dry


Hi!!

Have you cleaned the filter and the exhaust duct??

Lint plugs therm up, the heat sensor shuts off heating element thinking it is hot enough. Result: Clothes not getting dry.

Unplug duct and clean it, also clean the exahust passage of dryer. (where duct hooks to dryer)

Click below if this was helpful, Good luck.

Whirlpool 6.5 cu ft 5 cycle is not timing and drying clothes qui


First I would check to make sure your vent is not clogged or kinked. As far as the timer, the only fix would be to replace it. Unless of course you have the feature that detects the dryness and that would put you back at the venting problem. Good luck.
