Freezer Fan Icing Up

Hi,

Appears as though there may be a defrost problem.

This could be caused by a faulty defrost heater, faulty defrost sensor, blocked drain leading from under the evaporator unit in the freezer to the evaporator pan under the compartments or perhaps a faulty control board.

Here’s the troubleshooting section of the service manual. This will hopefully give an error indication which will tell you what the problem is, when you run the refrigerator in test mode.

I have the same problem. I won't put any money into this as mine is 8 yrs old. I unplug the fridge and take out all the shelves. I take a hair dryer to the back panel and unscrew it. remove carefully the panel to the side and use hairdryer to melt the ice. Put it back and wait for the next time the fan makes noise. Sometimes it can be a month or two others 3 weeks. Cheaper than a new fridge for now.

Yep my whirlpool has this issue also. When the fridge was still under warranty I had the repair people out here 3 different times and they never fixed it. Now it’s out of warranty and still freezes up. Have to take the back panel off the freezer and defrost the fan about once a month. I usually know when it’s about time to do it because the ice maker slows down on making ice.
