When Danielle and I returned from the grocery store<\/a> this evening we found that the fridge (a Maytag PBF2253HEB) was much warmer than it should be; somewhere around 60\u00b0F. When it was still this temperature after eating dinner it was time to try and figure out what’s going on. As the compressor was running and the freezer was still perfectly cold I figured that the duct between the freezer (where the cooling coils are) and the fridge must be misbehaving.<\/p>\n

Investigating the fridge portion of things showed that the servo which opens a damper in the fridge (allowing in cold air) was operating, so I started to look at the freezer. Just when I noticed some unexpected frost through the slats at the rear Danielle found this article<\/a> explaining how the freezer can frost up, leading to no airflow to the fridge and thus no cooling up there.<\/p>\n

It suggests replacing the control board<\/a> to resolve a problem with Adaptive Defrost Control. Before that I decided to do a manual defrost and see if that resolves things. I’ve had the fridge for just under five years with it running non-stop the whole time with a fair bit of ice sublimating in the freezer, so I figure that maybe enough frost could have built up in that time that the automatic defrost couldn’t overcome it.<\/p>\n

If the frost issue comes back quickly I’ll look into actually repairing it. I found a copy of the service manual here<\/a> (mirror<\/a>) and will just run through the diagnostics and replace the needed bits.<\/p>\n

The photo above is the evaporator coils inside of the fridge completely packed with frost. The part that appears to be a frost bottom shelf was a solid block of ice. Here’s a handful of photos taken while defrosting things, including what Danielle feels is an extremely dorky photo of me:<\/p>\n
