Tip & How-To about GE Profile Harmony DPGT750EC Electric Dryer

Service Mode for GE Harmony DPGT750EC

To find out what all of those sensors in your dryer are reporting, you have to enter Service Mode. To do so,

  1. Power on the dryer...or press "Home" if it is already on.
  2. Press "Home" and "Help" simultaneously until the dryer beeps.
  3. Choose your type of drying cycle and begin it.
You will notice on the bottom right of the screen a bunch of numbers. The top number will change constantly because that is the blower speed. If it is not getting up to @2,400 rpms, then you need to clean the blower blades and trap or take the blower motor out and re-solder all of the contacts inside the motor. Be careful and take note on taking apart the motor and putting it back together. Don't attempt this if you don't know what you're doing! Ask for help if you're not sure. And always unplug the dryer before taking it apart!!!

The numbers below that are the temperature setpoint and the actual temperature(air dry will result in zeros). The actual temperature should reach the setpoint unless the blower motor is not running- safety feature. Extra low setting resulted in a setpoint of 42 degrees Celsius? on my dryer, Low setting was 67 degrees C, Medium setting was 83 degrees C, High setting was at 100 degrees C. Other sensors include humidity sensor, vent temperature sensor, line frequency reading under OK VOLT(@60 US, @50 Europe), voltage(200-220) and countdown timer in seconds(last row). If the voltage is roughly half, check both breakers!

I hope this little tip will help you in your repairs!

I have model # MDE6700AYW (Maytag Neptune electric dryer) Error code T5, service codes 0, 19 and 76. Can anyone tell me what part needs to be replaced?


Check to see if your thermistor is bad by measure the resistance. It should be 10K Ohms at room temperature.
If it's bad, replace it BUT you have to CLEAR to error code.
1. Enter to Service Mode by press CHIME and TEMPERATURE keys for 3 seconds or until 3 beeps are heard.
2. Access Diagnostic Codes by pressing WRINKLE PREVENT. A d will be displayed. Rotate the CYCLE SELECTOR KNOB in either direction to read it.
3. Press SENSOR DRY and TIME keys for 3 seconds to clear it.
4. Power OFF to exit Service Mode
5. Power ON
Here is a link to the part in case you need it.

my Fisher paykel dryer does not heat


Thermostat Cutout – Manual Reset (Electrical)
Type SPST 30 Amps/240 Volts AC
Trip Temperature 212°F (100°C)
Diagnostic Mode
Entering the Diagnostic Mode
(a) Turn the power supply to the dryer on.
(b) Press and hold the Auto Dry down button, then press the Power
button.
The dryer is now in level 0 of the diagnostic mode. After initial entry into the
diagnostic mode, the Start/Pause button operates the dryer as normal. Press
the Auto Dry up or down buttons to scroll through the fault levels.
There are several levels of diagnostics, most of which are used in
development and production. These levels may bring on various LEDs, but
the level of use for the service technician is that of the last fault.
Last Fault
To enter the last fault diagnostics, enter the diagnostic mode as described
above, then press the Auto Dry up button three times. The last fault will be
displayed on the drying progress LEDs
Conductivity Contact Impedance Check
To enter the conductivity contact impedance check, enter the diagnostic mode
as described above, then press the Auto Dry up button five times. In this
mode, touching damp clothes or fingers across the conductivity contacts will
cause the LED display to change. If the contacts, or the harness to them,
have gone open circuit, no change will occur in the LED display. This is a
useful method of checking the integrity of the sensor circuits.
To exit the diagnostic mode, press any cycle button.
Entering the Data Download Mode
(a) Turn the power supply to the dryer on.
(b) Press and hold the Auto Dry down button, then press the Power
button. This enters the diagnostic mode.
(c) Press the Regular button.
Encoded data is transmitted serially out the red Auto LED, and is be captured
by an optical download pen attached to a PC where “Smart Tool” software
interprets the data to aid servicing.
To exit, press the Regular button.
Entering the Showroom Mode
(a) Turn the power supply to the dryer on.
(b) Press and hold the Air Dry button, then press the Power button.
The LEDs will flash in a random sequence.
To exit, turn off the power supply to the dryer at the wall.
Tell me what sort of faults codes you can come up with and I will tell you what it means but in the meantime reset the limit and clean out the lint problem, open the stopped up vent. That dryer has to breath or that safety will kick out again. I have the manual
