Darren for Model Number plhs67eesb4 2006 fridge. Freezer and fridge cool and then warm up.. It seems like it cycles. When auto defrost comes on it cools down to zero then warms up again after evap coil frosts up. I replaced control board only to find out it throws a 4 code on fridge side of control board. Are the new boards compatible with the old dampeners? The old board did not throw an error code. Also it didn't change a thing. Still cycling. Also only top half of evap coils frosts on the outer half?
Answer Hello Darren. It should be compatible. However, you will need to check the damper and see if it is bad on the unit. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
