Hello
The issue is very vague. many possible problems. is compressor running? are evap and condensor fans running? is their any frost pattern on evap coils? alot of those answers will help me diagnose properly. for the time being putting into test mode off tech sheet would atleast reset board. if board cannot be reset and only flashes 0 0 then can either be problem in main control or user interface. most likely sensor was not issue. will have to get running and see what issues are once board is atleast calling for cool. Hope this helps

Hello
Do you have any error codes ? If not you could have many possibilities from a Clogged lint screen, restricted vent system, thermistor issues, gas valve dropping out, main PCB defective, Software Version not up to date . See technician diagnostics sheet link below and testing procedures below. Matt Ace technician

Service Mode
Press Mixed Load Bell + Temp for 3 seconds in normal mode
until it sends out a beeping sound
If pressing same combo of buttons it will leave this mode

Software Version Test Mode
How to Enter:
Press Temp key for 3 seconds (until beep)
Note: ex) In case of “U105” U0 means major version “v1”
05 means version “05” If press Temp key in software version
mode it will return to Service Mode

Gas Valve Testing
Unplug connectors and test valve terminals
(its numbering is from the front terminal.)
Check across terminals #1 and #3 (Booster Coil). 550 Ω
Check across terminals #1 and #2 (Holding Coil). 1350 Ω
Check across terminals #2 and #3 (Both coils in series). 1900 Ω
Check across terminals #4 and #5 (Secondary Coil). 1300 Ω

Moisture sensor & Thermistor

Hi. I have attached the service manual for this unit. Has the machine given any error codes? You will find the error codes in the manual. I do not see a way of going into diagnostics to retrieve any stored errors. I would check your thermistor for proper resistance. Also, check for a loose power cord or outlet that may be losing voltage. Check for proper power and check the power cord at the terminal block for loose or burnt connections. If everything checks out good, you may have a faulty control board. check for burnt marks on the board especially at the heat relay.

Sounds like your having a problem with the “auto dryness” sensing feature on the unit. If you run the unit on time dry will it stay running? If so There is likely a problem with the control board. The moisture sensor really cannot go bad as they are just two strips of metal that create a short when a wet piece of clothing comes in contact with them. I have not personally fixed this issue however I have came across this once in the field. I tested the moisture sensor and it checked out fine and gave the customer an estimate for the control board. They declined the repair so I cannot defininitely say this will rectify the issue however that is the component I would replace if the unit runs on time dry without shutting down. Sounds like your heat circuit is working properly. Seems like the unit is going into basically the “cool down” mode. Hope this helps.

See parts breakdown below. Do you have power coming in the burner # 8273994. Have you tested the burner ? If not see video link. If burner is testing good go to the switch control # W10190398 and W10190396 Board, Control see tech sheet for testing. Matt

Hello

Did you disassemble the entire area where the condensate pump is and remove the slimey gunk that is in there? This takes about an hour. The control is not reading the moisture sensor, therefore it will shut down quickly. The Duet dryer will do the same thing. Check the moisture sensor connections to see if it fails, the control may be at fault for not reading moisture. Be aware that this Auto setting must be used with a full load of items, not just a few things. If drying a small load, better to use the timed cycle so the sensor does not cause an issue.

See the technician service guide link below for your model. Also add a link to a ( GTD ) model dryer with videos. Matt Ace technician

Too many digits in your model number . The actual model number should be 110.45088404. The F33 fault code indicates that the wiring connection between the pump and CCU (central control unit or main control board) is lost. This can be caused by a loose wire harness connection at the pump or the CCU. It could also be caused by a bad pump motor.
The first step in troubleshooting this problem would be to unplug the washer and check the wire harness connections between the pump and the CCU. To access the pump, remove the screws on the bottom of the lower service panel on the front of the washer. Pull the service panel out and down to remove it from the washer. To access the CCU, remove the screws on the back of the top panel and pull the top panel off of the washer. The wiring diagram below shows the connector for the pump on the CCU.If the wiring connections are okay, check the resistance of the pump circuit through the wiring connection at the CCU. With the washer unplugged, the resistance through the wires that connect to the pump should be around 12.3 ohms. If the circuit is open (measures infinite resistance), check the resistance on the leads of the pump motor. If the motor is bad, it will need to be replaced. If the motor measures the proper 12.3 ohms, then the wiring harness would need to be replaced. If the pump circuit is okay and the F33 will not clear, then the CCU will need to be replaced. since yo have replaced both CCU and drain pump you must have a bad connection or bad wiring harness. If you cannot find loose connection you will have to replace main wiring harness.

Hello
I would start with verifying the water level, most poor wash conditions are due to low or no water to dissolve the detergent. Other items to check:
1) Poor wash due to draining, dispensing, and/or temperature problem.
2) Plugged water inlet valve . – Low water pressure
3) Spray arms not rotating, busted / cracked or plugged.
4) Plugged or damaged coarse screen.

If you have a frost build up on the evaporator and you have verifyied the defrost heater and defrost thermastat are closed with full continuity . The only other possibility is the Board Asm Main Control  (Replaces: WR55X10603) WR55X10942P. Matt Ace technician 

Hello
See diagnostc service manual technician link below.There are many possibilities with you issue , I would start out on page #10 troubleshooting and work down the page to address every possible part until you get to the core of your issue. Go to page #22 for control panel diagnostics. Go to page #23 for main PCB daignostics. Matt Ace technician

Diagnosis Function for display panel
* Automatic diagnosis makes servicing the refrigerator easy.
* When a defect occurs, the buttons will not operate; but the tones. such as ding. will sound.
* When the defect CODE removes the sign, it returns to normal operation (RESET).
* The defect CODE shows on the Refrigerator and Freezer Display.

Test Mode main PCB see on page #23
TEST Mode
* The Test mode allows checking the PCB and the function of the product as well as finding out the defective part in case of an error.
* The test mode is operated by pressing two buttons at Display panel.
* While in the test mode, the function control button is not recognized, but the recognition tone (beep~) sounds.
* After exiting the test mode, be sure to reset by unplugging and then plugging in the appliance.
* If an error, such as a sensor failure, is detected while in the test mode, the test mode is cleared and the error code is
displayed.
* While an error code is displayed, the test mode will not be activated.

The control system used on the JED4430 series downdraft cooktop has no diagnostic operation mode or temperature adjustment mode. Go to page #2 for the transformer and user interface diagnostics. Then to pages 3-5 for the diagnostic procedures on the the elements. There is one service bulletin on your product , see link below. Matt Ace technician
