Maytag Side X Side Refrigerator adaptive defrost check


To check the defrost circuit , unplug the refrig and inside the refrig section at the top
about 2" in from each side in the back , there are "D" slots to put a finger in , and pull
downward and foreword , to remove the control panel cover . Once removed , there is a 1/4"
screw on each side holding the adjustment indicator panel on , 1 phillips screw behind both
light bulbs , and 1 screw holding the complete panel to the rear wall . After removing these
5 screws , at the top right corner , with about 6-8 wires going to it , is the adaptive
defrost board ( adc ) . Sometimes you can see the electronic board and on newer refrig's , a white
box will be seen . Inside this box , is the adaptive defrost control . Disconnect the plug
going to the board and on the right side of the PLUG , the far right wire is yellow , then
another color , then white . Using a small insulated wire with both ends stripped , insert
one end into the yellow wire hole and the other into the white wire hole . This will send power directly thru the defrost bi-metal ( thermostat ) AND
heater to check if they are good .Plug the refrig back in . Now , if you have a clamp on amp meter , clamp around the jumper wire while pushing in the light switch ( to turn off the light to get only defrost amps ) which should be 3.5 or above indicating bi metal and heater are good and adc is bad , OR , wait about 3-5 min and
look for a red glow at the bottom of the inside freezer panel , which will be the defrost
heater or listen for sizzling which will be the frost melting and dripping onto the heater
.If NO red glow , watch for a spark while removing the jumper wire you installed , from the
plug . If a spark IS seen , then the heater was on and the heater AND bi-metal are good . If
you see the red glow , hear the sizzling , or see the spark , then the adaptive defrost
board should be replaced . If no glow , sizzling or spark , then unplug the refrig and
reinstall the refrig control section .
Remove the food in the freezer section enough so that the 2 screws holding the lower freezer
panel on and the freezer panel , can be removed . Remove the panel . If the heater (black
element at the bottom of the coils ) wires are visible , trace them to the top of the coils
and disconnect . Use an ohm meter to determine if the element is good ( should show continuity ) . If the element IS
good , at the top of the coils , is a 1" cylinder with 2 wires , clipped onto the coils .
This is the defrost thermostat ( bi-metal ) . Replace this part if the element shows good .
If the element shows bad , replace the element . NOTE 1 : sometimes the element and the
bi-metal come wired together and the replacement part comes with a new heater and bi-metal
already wired together . This would be the advisable replacement part . However , each part
can still be replaced individually . NOTE 2 : If looking at the bi-metal and the top plastic
" cap " looks cockeyed , replace the bi-metal as moisture has gotten inside and disturbed its
designed function .

Have a Frigidaire GLHS68EE. The freezer side appears to be working normal but the frig side doesn't get cooler than 53 degrees. Any suggestions?


Hello,
Sounds like you have a defrost problem since the freezer side is working ok . It probably is not blowing cold air into the refrig side , so to check the defrost circuit , unplug the refrig and inside the refrig section at the top about 2" in from each side in the back , there are "D" slots to put a finger in , and pull downward and foreward , to remove the control panel cover . Once removed , there is a 1/4" screw on each side holding the adjustment indicator panel on , 1 phillips screw behind both light bulbs , and 1 screw holding the complete panel to the rear wall . After removing these 5 screws , at the top right corner , with about 6-8 wires going to it , is the adaptive defrost board . Sometimes you can see the electronic board and on newer refrig's , a white box will be seen. Inside this box , is the adaptive defrost control . Disconnect the plug going to the board and on the right side of the PLUG , the far right wire is yellow , then another color , then white . Useing a small insulated wire with both ends stripped , insert one end into the yellow wire hole and the other into the white wire hole . This will bypass the adaptive board and send power directly thru the defrost bimetal ( thermostat ) AND heater to check if they are good .Plug the refrig back in . Now , wait about 3-5 min and look for a red glow at the bottom of the inside freezer panel , which will be the defrost heater or listen for sizzling which will be the frost melting and dripping onto the heater .If NO red glow , watch for a spark while removing the jumper wire you installed , from the plug . If a spark IS seen , then the heater was on and the heater AND bimetal are good . If you see the red glow , hear the sizzling , or see the spark , then the adaptive defrost board should be replaced . If no glow , sizzling or spark , then unplug the refrig and reinstall the refrig control section . Remove the food in the freezer section enough so that the 2 screws holding the lower freezer panel on and the freezer panel , can be removed . Remove the panel . If the heater (black element at the bottom of the coils ) wires are visible , trace then to the top of the coils and disconnect . Use an ohm meter to determine if the element is good . If the element IS good , at the top of the coils , is a 1" cylinder with 2 wires , clipped onto the coils . This is the defrost thermostat ( bimetal ) . Replace this part if the element shows good .

Good luck in solving this....

the cooling coils are icing up. Have checked the defrost element with ohm meter it seems to be good. thermostat looks to be intact and sealed. Does this mean that I have a defrost control problem?

I have a Jenn Air side by side re***erator/freezer model JDC2389GE. The right side (***) stop cooling this week. Freezer side still working but frost has built up inside on the back middle section. This unit came new with the house we bought in 2003. Any thoughts?
