We have a Whirlpool SD20 RSB33 Side by Side
The freezer side is now periodically malfunctioning; unit 3 years old. The fridge side appears to be working fine. The freezer alarm sounds and when we press the OK button the alarm stops. However the freezer temperature does not return,
When we unplug the unit for an hour or so and then re-connect, the freezer returns to the desired temperature within approximately 15 minutes.
The unit works fine for about 12 -24 hours and then the same thing happens. This cycle has now been going on for a week.
We have checked the seals, verticality of the unit, thoroughly vacuumed the lower sections front and back (first removing the grill covers).
Any suggestions?
There is a guy in South Yorkshire who can repair these boards.
