My dryer has worked without flaw since Oct. 2009. I went to start a new load & everything powered up fine & all lights came on, but the dryer would not start. The light next to the "sensing estimated time" came on & drum would not turn. So after checking things out & stuff, I found my thermal fuse was blown. I replaced thermal fuse & after one drying cycle, the fuse blew again. Alright, now it was time to dig deeper. I put another thermal fuse in & it has yet to blow, but now the problem is that the heater is WAY TO HOT when drying clothes! It seems like the heating element never shuts off. I have tested and tested & I thought the troubleshooting guide under the top lid lead me to the right fix, an outlet thermistor. Well, I installed it tonight & the same symptom, way to much heat way to quickly. I mean you can barely touch the clothes or the exhaust vent. I thought i have followed all troubleshooting up to this point (checking ohms, continuity,etc...)
Any help in direction would be much appreciated!

Have you checked to see if the heater element is grounded?
Unplug the unit and both wires for the heating element.
Measure across the heating element, should be 8 to 12 ohms.
Then measure from each side of the element to it's case, both should be infinite ohms. |

If heater coil checks out ok, you may have a stuck heat relay on the machine control board. Unplug dryer, access control board and unplug red and black wires from the relay (large square box in corner of board). Check continuity across terminals of relay. If you read continuity, relay is bad and board must be replaced.

Eric Thanks to you also for the knowledge and helpful direction.

Thanks guys for the direction to help me out! I passed on the info to my brother in law, who is an electrician, and he did both & found that the heating element checked out. he also tried the red/black wire suggestion @ the control board - everything was ok there also.
Now I am at a loss of what to try next. It has been nearly 2 weeks since this happened & my wife is getting kinda pissed off not having a dryer. I have had a couple people tell me try a THERMOSTAT. It makes sense & all, but I don't want to throw another part at the dryer if it is not needed.
Does anyone think a faulty moisture sensor would cause all this madness??

Here are your parts Parts for Maytag MEDE300VW1 Dryer - AppliancePartsPros.comSee the attachment for the tech sheet. As you can see your unit does not use a thermostat for temperature regulation. It has a hi-limit thermostat but this is a safety device with a thermal cutoff as a backup safety device. Run the diagnostics to see if everything passes. Since the thermistors and the heater check out OK I would say the problem is the control board. FYI if purchased from AppliancePartsPros, they will let you return it if it does not solve your problem. Please see theur return policy. |

This is the same tech. sheet I have been using since the problem began. I did put the dryer into Diagnostic Mode & it threw the F28 code at me. So I followed the steps to test the moisture sensor & I did hear a continuous beep tone when I ran a damp cloth across the 2 sensor bars. It tells me test the harness & that's where it gets a little confusing for me.
Could this something that is unrelated to my problem or does something about this make sense to any of you guys?

Faulty moisture sensor would not cause this problem. It's not even used in timed dry cycle. I think you got the error code because you are testing without any wet clothes in the dryer. If you run a cycle without wet clothes, it won't detect moisture and will store the code for that. The control board uses the thermistor to detect temperature and operates the relay to cycle the heater on/off to maintain temperature. Either the board is bad or there is an air flow problem.

Eric Well, a new board is not what I wanted to hear, but if it fixes the problem, that's great. It will be cheaper than buying a new dryer that's for sure.
