Question about Refrigerators
Control board does not respond at all and just blinks the number 5 in both displays.
MAY HAVE A BAD START RELAY OR CAPACITOR ON THE COMPRESSOR , CAN BUY A INEXSPENSIVE 3 IN 1 HARDSTART KIT AND BY PASS THEM , NOT THAT HARD TO DO, COMES WITH INSTRUCTIONS> BY THE WAY DO U HEAR ANY CLICKING SOUNDS FROM COMPRESSOR? BUT U MAY ALSO WANT TO CHECK UR COLD CONTROL THERMOSTAT IF IT GOES BAD U MAY GET A NON START ALSO HAVE IT CHECKED FOR PROPER VOLTAGE AND OHMS RESISTANCE WHEN IN THE ON POSITION
A BAD DEFROST TIMER CAN SHUT DOWN COMPRESSOR HAVE IT CHECKED WITH MULTI METER.
to check the defrost timer, u can get by and test manually by placing a small screw driver into the tiny slot or hole underneath the timer and turn slowly clockwise till u hear 1 click. this will engage ur defrost cycle in about 15 minutes u should be able to come back and feel the heat in freezer as it melts the ice providing ur terminator is not bad?
Another way to test it is with a multi meter. Remove timer it from fridge and you will see 4 prongs numbered 2,1,4,3 in that order. Place ur meter prong on prong 1 & 3 (if your fridge has a capacitor wired in series with the windings, then u check for micro fares rather than OHMS) If u cannot confirm this test, still try the next.
Take ur meter prong and connect to prong 1 & 4, it should read resistance or ohms ( closed) now remove prongs and place on prong 1 & 2, this should now read infinity or open (no ohms) now take a small screwdriver place it in the tiny hole or slot under the timer. Turn it clockwise slowly till u hear 1 click. Now ur 1& 2 should read closed ( showing ohms or resistance) now place meter prongs on 1 & 4 and you it should now show open ( or no resistance - no ohms) this is how u know ur timer is good, Remember when testing for ohms ADJUST meter to use a high ohms rating in the thousands as the resistance is very high in OHMS. And adjusting to low ohms rating may give a false reading or not show the proper resistance..
AT TIMES YOU MAY HEAR THE COMPRESSOR CLICK OFF AND ON OVER AND OVER. Signs of a bad start relay or capacitor. Check with an OHMS meter for continuity (ohms) and voltage, capacitor can be checked for Microfares.
To check ur compressor with multi meter:
Disconnect and remove the relay and capacitor from compressor, somes located next to compressor in a casing.
You wills see 3 prongs coming out of compressor. 1 goes to ur srtart winding, 1 goes to ur run winding and the center goes to ur ground.
Place ur meter connector or prong on the start prong and the other on the ground (center prong) take note of the reading in OHMS for example 5 ohms.
Next place meter prong on run prong and the center ground prong agin. Take note of the reading in OHMS. Example 4 ohms
Next place meter prong on the start prong and the other on the run prong, now take note of the reading example 9 ohms. Now match the total of this ohms test with the total of ur two separate test. 9 ohms, if they match ur ok give or take 5 percent plus or minus. One more test to make to test of there is a short in compressor attach meter prong to ground prong and rub the other end of meter prong to metal ( scrape the metal clean of paint and test on metal surface not painted surface. If it shows continuity or ohms , u have a short in ur compressor. It should show infinity

This type of diagnosis will require taking voltage readings at the control board with a meter to find the root cause of the failure. Please see the rest of the information provided & the images below for the accessing, testing & replacement instructions.
1). Put the washer into the Diagnostic Test Mode per the Tech Sheet. 2). Did the Right Hand Interface light up? 3). IF the Right Hand Interface did not light up in Step 2 check for 5 VDC on the UIP3 wire connector coming off of the control board to the Right Hand Interface from (Pin 1 to Pin 2) and from (Pin 1 to Pin 3). 4). IF you do not have the 5 VDC then remove the MI3 connector from the Machine Control board. IF the display lights; replace the Motor Control board. IF the display does not light; replace the Machine Control Board. 5). IF you do have the 5 VDC then replace the Right Hand User Interface. 6). IF the Right Hand Interface does light up. Lock the controls by pressing the control lock button for 3 seconds. 7). Once the control has been locked press the power pad. IF the control lock light blinks when the power button is pressed it tells us the power button is sending the output from being pressed to the right hand interface but the right hand interface is not responding and will need to be replaced. 8). IF the control lock light does not blink when the power button is pressed replace the center user interface.
