Dryer heats in a 'no heat' selection

If your Maytag MDE4658AYW electric dryer is running hot on all settings, even on air fluff, it is likely that the heating element is not working properly. Make sure that the heating element is securely connected to the dryer and that the power switch is in the "on" position. If the problem persists, you may need to replace the heating element or contact the manufacturer for assistance.

Make sure a heating cycle is selected. Air and Fluff cycles do not use heat.

Make sure that both phases of 120 volt power are energized (total of 240 volts between the 2 phases).

Most likely the heating element is damaged, which usually means there is no heat at all. A dryer with 2 heating elements will have some heat, but not have enough, when 1 heating element stops working. A dryer with 1 heating element can partially fail and have partial heat, too.

Instructions

1. • 1 Check the cycle selector control to make sure a heating cycle has been selected. The selector should be in an "Off" position when not in use, but it should be turned to a drying cycle when in use. On some models, make sure you are not accidentally running the dryer on the "Air" cycle, which does not use heat.
     
   • 2 Check the gas supply valve to make sure it is open if your dryer is a gas dryer. If it is not open, just lift the valve open.
     
   • 3 Look at your house's main breaker box to determine whether a circuit breaker is tripped. The electric dryer runs on 220-240 volts and has a double breaker. If the breaker for the heating element is tripped, the drum may tumble the clothes without heat. Turn the dryer's breakers to off, then back on; test whether the dryer will produce heat.
     
   • 4 Consult a technician if troubleshooting does not resolve the problem.
     

This E68 is a stuck keypad.


The error E68 means the CCU has sensed a stuck button on the console. MANY times this is a false error and means that either the CCU or interface must be replaced, but SOMETIMES, there really is a stuck button. Try to run a diagnostic using the instructions I have provided below, let me know if you need any help with it.
1. Press and hold Select and Cancel buttons simultaneously for 6 seconds to reset the control. The buzzer will sound
1 time and " res" will be shown briefly in the display.
2. Immediately after, rotate cycle selector knob 5 turns counter-clockwise to the second position from the bottom.
Press and hold the Options and Cancel buttons simultaneously for 2 seconds. The control will enter test mode,
the buzzer will sound 3 times and all LED's will rapidly flash.
After entering the test mode, the cycle selector knob can now be rotated to select the following tests:
Rotate the cycle selector knob clockwise from the starting position:
0 turns: All LED's will flash.
1 turn: Drive motor runs; heat source is on. Drying LED is lit. "H" and the control thermistor reading will toggle
back and forth in the display.
2 turns: Drive motor runs; heat source is off. Cool Down LED is lit and "AF" (Air Fluff) is displayed.
3 turns: Drive motor runs; heat source is off. Drying and Cool Down LED's are lit and numbers appear in the
display showing moisture sensor readings. Opening the door (press in on door switch plunger) and placing
a finger on the both moisture sense bars at the same time will make the numbers decrease. In controls that
do not have a digit display, the More Dry LED should be ON. Opening the door (press in on door switch
plunger) and placing a finger on the both moisture sense bars at the same time will make the Damp LED
come on.
4 turns: Drive motor runs; heat source is off.
Key test:
a. When the Temperature key is pressed, all the temperature LED's should light.
b. When the Dryness key is pressed, all the dryness level LED's should light.
c. When the Options or Select key is pressed, all the Option LED's should light.
d. When the Start/Pause key is pressed, all the cycle status LED's should light.
e. When the Cancel key is pressed, all the cycle status LED's should light.
5 turns: Drive motor runs; heat source is off. Cool Down LED is lit. Control thermistor reading is displayed.
6 turns: Drive motor runs; heat source is on. Drying LED is lit. Control thermistor reading is displayed.
7-11 turns: All LED's will flash
To EXIT test mode, press and hold the Select and Cancel buttons simultaneously for 6 seconds or disconnect power
from dryer. Dryer will be reset for regular operation.
If you cant even enter this mode at all, your interface will have to be replaced. There is no way to determine whether its the interface OR CCU, but in my experience, it's usually the interface that ends up needing replacement. Here is a link to the interface board.

This allows you to adjust the temperature to match what you are drying. Some fabrics and clothes require low heat or you may only be drying a small amount of clothes and don't need much heat. You also may not want high heat to avoid shrinkage of some clothes.

No heat problems are caused by several things.
First lets do the easy thing and turn off the Dryer CB by pushing it HARD to off and then back on. Re-test for heat.
Next try different cycles as in Air Fluff, Delicate, regular etc... Air fluff is no heat but see if it heats on other heat temp selections. If you get heat on a different heat selection then the problem is probably an open thermostat. If you still get no heat the most likely suspect is the heating element. If the heating element is fine then your looking at the motor switch or wiring as the problem. Component of last resort to replace is the timer.
At this time I suspect either a high limit thermostat or an open heating element.
Mond you since you did not include your complete model number this response if for an electric dryer. IF your dryer is gas respond with a model number please so I can point to other things that cwill cause a no heat symptom.

Thanks for choosing FixYa, Kelly

I will assume this is an electric dryer.

When asking for help, you should include the brand and model number to help get a great answer.

In my experience, these are the possible problems in order of how often they happen.

1) Thermal overheat sensor fails. This is a small electrical device that will turn off the heating element if it thinks the dryer is getting too hot. It will have 2 wires connected to it and a silver colored round metal piece that senses the heat. When this part fails, the heater will not turn on. Disconnect the wires from this sensor and verify that it has zero (0) ohms across the two connectors.

2) Heating element could be burned out. Disconnect the two wires from the heating element and verify that it has a low resistance. Replace it if there is no resistance.

3) The thermostat has failed. There is a part that monitors the heat in the oven and turns the heating element on and off. You test it the same way you test item #1 above.

4) Some dryers have a FLUFF setting where the dryer only blows cold air. The switch that selects the heat settings could be broken. You will need to test this switch by looking at the electrical schematic for the dryer and testing the switch as indicated.

5) The knob on the switch that chooses the heat setting could be pushed onto the shaft in the wrong position so it points to "hot" when it is actually set to "fluff." The simplest way to test this is to choose a heat setting one click, either direction, from the one it is on now. If you get heat, the knob is pointing to the wrong place.

the first thing to check is the ignitor .how ever there is a thermal fuse located on the exhaust duct inside the dryer that may be bad this woulld cause the unit to run and not get hot.this needs to be checked with an ohm meter for continuity there is more than one thermal fuse so check them all just to be sure.i hope this has helped.please let me now how things turned out.good luck

Good Afternoon,
Is this dryer Electric or Gas?

• There are two house circuits/fuses in an electric dryer's circuit.
  If one of them is tripped/blown, the drum may turn, but the heater will not operate. Reset the circuit breaker or replace the house fuse.
• Outlet wired incorrectly.
  Have a qualified electrician verify that the supply voltage is correct.
• Gas supply valve to a gas dryer is not open.
  Open the gas supply valve. See Installation Instructions for details.
• LP gas supply tank is empty or there has been a utility interruption of natural gas.
  Refill or replace the LP tank. Call your natural gas utility company.
• Dryer does not have enough air supply to support the gas burner.
  The dryer needs space around it for proper ventilation. Do not stack or place laundry or throw rugs against the front or back of the dryer. See Installation Instructions for details about installing a dryer in a closet or alcove.
• Incorrect cycle or temperature has been selected.
  If the Air Fluff cycle or temperature is selected, the dryer will tumble without heat. Each cycle ends with a Cool Down period during which the load tumbles without heat. Check the location of the indicator on the Cycle Selector knob.
