E05 and E06 is the error codes for a faulty stack flue sensor. try changing the sensor first is the cheapest. if that doesn't work check for corrosion on control board in which case will have to change out board.

Review the trouble shooting guides in your owner manual. You will find it says to look at the LEDs on the back of your main control board. They are difficult to see with the board installed, if  you can't identify which LED is lit just remove the 4 small screws at the corners of the board,remove it a see which sensor LED is lit. You can bet it will lead you to an area to investigate, ie temp sensors, air flow sensors, water temp sensor etc. Hope this helps. I'm in the middle of the same troubleshooting process.

Error code e61


Identification
  • GE dryers use three-character codes that display on LCD screens. Every code starts with "E" and is followed by a two-digit number.
Power Failure
  • When your home loses power, the "E01" error flashes on the screen. Reset the dryer memory by unplugging the device, waiting 30 seconds and plugging it back in. The error code will disappear.
Thermistor Errors
  • Errors "E02," "E03," "E04" and "E05" are thermistor errors. The thermistor, when operating properly, reads the temperature of the dryer. Errors E02 through E05 indicate the thermistor must be replaced.
Effects
  • When there is an error with the door switch and sensor, the "E60" error code will appear. An unbalanced door will produce the E60 code. Try to close the door gently and listen for the click. If the error remains, the door switch may need to be replaced.
Control Board Errors The control board sends signals from the controls to the dryer. When this fails, errors "E61," "E80" and "E81" appear. Contact GE service or install a new control board for the dryer

Master temp 400 with E05 error message, already replaced stack flue sensor, thermistor, and igniter. Any suggestions?


I have the same exact problem with this unit. Obviously getting gas to the unit, because it runs and pumps out some serious heat for a short time, but then kicks off. Did anyone ever figure this out or did you buy a new heater? :-)

Try changing the "stack flu sensor". It could be the sensor is bad or the sensor could be detecting a bigger problem. The sensor can not be jumped out.

E05 error message & Service light on What does this mean? Is it something that can be fixed easily?


E05 is Ignition / Flame Failure in this model.
The most common cause of this is a bad ignitor, but can also be a bad flame sensor or ignition module.
Here is a link to the original manual with a very good service and troubleshooting section to accurately describe how to do this. I will put a simpleanswer on here, but it might be neccessary to do some reading too.

Turn off power to heater.
remove both front doors to compartment
Turn on power to heater.
Make sure the mode is set to pool/spa on.
turn temperature up to desired
within 30 seconds the fan should come on.
once the "thermostat" light comes on in the front LCD then pay attention to the ignitor

The ignitor should now be glowing. (if ignitor dosent glow, repeat this process and use a multimeter to ensure power is getting to the ignitor)ignitor part number is 471602

after 30 more seconds you should hear a little "pop" coming from the gas valve.
This is the gas valve opening to try to ignite. If the ignitor is working and the burner ignites, and then goes off with an E05 code, then this would indicate a bad flame sensor (part number 471603)

in rare cases, this code can be tripped by a lose wire on either of these parts.
The parts diagram in the manual on pages 33-34 will help to guide you where to look for these parts. It is always best to familiarize yourself with the heater before work is done.
