Whirlpool bottom freezer cool, not frozen, has frost clump.
A neighbor of mine has a french door Whirlpool fridge model WRF535SMBM00 that is currently only cooling the freezer to the same temperature as the fridge. There is a clump of frost about the size of a head of cauliflower (but not as thick - maybe 2") in the upper right hand corner of the freezer.
I am guessing this is a defrost problem, but looking at the service guide (https://www.scribd.com/document/34169130...) diagnosing what part of it is going bad does not seem approachable. Anyone have something I can recommend for her to try or I can do in a visit to possibly prevent having to call a maintenance worker to troubleshoot it professionally?
I am pretty handy with car and other household repairs, but last time I had to use a multimeter to try and figure one of these out I did not feel like I was measuring things right and did not resolve the issue.
Is dit een goede vraag?
