The ignitor is coming on so that means you have power to the gas assembly. Next the flame sensor should shut down the ignitor when the bi-metal inside it bends from the heat. This kills power to the ignitor, which allows for the power to activate the coils. The coils snatch open the gas valve and allow for ignition. The raw gas hits that screaming hot ignitor and ignites into a glorious flame, raising the temperature inside the drum. While that flame is on, the control thermostat is monitoring the heat within the drum. When the temperature gets to a round 140 F then the power gets killed to the gas assembly by the control thermostat. If all of that seems to be happening for say, the first time, then suddenly the ignitor comes on then shuts down and no flame comes out, then you have weak and intermittant coils. Replace these puppys:

No Heat- Dryer will not dry clothes, the pilot light will light for a few seconds with a glow. I have changed the coils and the thermal fuse. Don't know what else to try.

Even though it glowssometimes it is still not working properly. if you dryer is gas check out this gas no heat tip....

Hi.

Be sure that you have checked the thermal fuse. The part is tested using a multimeter set on Ohms (impedance). Remove the fuse from dryer and read impedance touching the fuse contacts with the two multimeter probes. If impedance is Ohm infinity (open), then the fuse is bad.

If the fuse is OK because tested good or replaced, then the problem is either one of the three thermostats located in the heating group, or the heating element. All parts are tested similarly to what described for the thermal fuse. If any of the parts read open (infinity), then the part is faulty. After finding the defective part remove all the lint from heating assembly and air duct. The lint causes overheating and blows thermostats, fuse or element.

Regards.

Dryer will not heat. Mod: 11066652500 Ser: MS2302035


If your dryer is electric, it's most likely a thermal cut-off or the heating element. if it's gas, it's probably the thermal fuse. i do lots of these each week. 90% of the time it's what i just explained. good luck :)

Everything seems fine but will not heat up I checked continuity, on every thing and it seems fine and I did the more less more less and all codes came up fine took the heating element out and it seems fine...


First things first...Are you sure that you have 220 volts to the dryer? Just because the motor runs doesn't neccesarily mean you have the proper voltage. Also check the connections where the cord comes in to see if they are tight and intact.
