Kitchenaid KSBP25INSS00 Freezer at 24 degrees

[Rusty Wrench]

The freezer is only at 24 degrees while fresh food section is holding the 38 degree setpoint.  Mullion and door gasket area are very hot.  Condenser fan is working.  There is no "energy saving" button on this model.  Are there mullion heaters which have gone haywire or what?  I appreciate any help.

No mullion heater on this model. Even if there were i can run at full blast should not afect the freezer to that point. 

Does a cigarette heat up a ice rink?     ...... Nope, neither does the mullion affect that much.

HOWEVER. This model does have the yoder loop running through the mullion. And it will get hot if the condenser is running hot, or unit under high load. 

This yoder loop performs the same function as a mullion heater, but is heat rejecting refrigerant tubing not a heater. ( may just be semantics here)

the only reason it is hot, is a hot condenser. 

Clean condenser/ check fan, let it sit for a hour and recheck

Are you sure the condenser fan is running?

a lot of people mix up condenser and evaporator. 

You are checking the one in the back?

Condenser fan was running, but irregularly.  Solution was a new main computer - thankfully available from Whirlpool but under a different P/N than the original. The replacement is re-engineered to cover a wide range of products.  The original P/N shows as NLA.
