Refrigerator and freezer not cooling

Brand:

Whirlpool

Model:

ER2CHMXPL01

This refrigerator initially had an issue where the freezer was freezing excessively, producing a lot of frost. Over time, the refrigerator section stopped cooling properly. When temperatures were colder, both compartments functioned, though there was some humming noise. Now that it's getting warmer, other they both have stopped working. I removed the rear cover and found that the fan is running, but the compressor feels warm. Can you provide guidance on troubleshooting this issue and getting the refrigerator back to working condition? Thank you in advance.

Hi @fredl95584

Assuming that you meant that the condenser fan was working, check if the evaporator fan inside the freezer compartment behind a panel at the back of the compartment is running.

The fan will run as long as the compressor motor is running and if both doors are shut. It will stop when a door is opened (either door) and start again when the door is shut. The compressor will keep running when a door is opened.

Manually operating the door switch will simulate that the door is closed therefore you can check if the fan is working or not when the compressor is running and with a door open

If the fan is not running due to it being iced over, then there's a defrost problem with the refrigerator.

This could be caused by a faulty defrost heater, faulty defrost timer, faulty defrost thermostat or the drain leading from below the evaporator unit to the evaporator pan underneath the compartments near the compressor may be blocked, preventing the defrost meltwater from draining away allowing it to refreeze and build up on every subsequent defrost cycle.

Here's a link that has a video that shows how to get to the fan.

If the fan is not running and is not iced over, then there's a problem with either the fan motor or the power supply to the fan

If you find the problem and it's a faulty part that needs replacing, here's the parts list that is useful. Locate the wanted part in the list and note the part number that is shown with it. Search online for the part number only to find suppliers that suit you best.

Hi @fredl95584

If the evaporator fan isn't operating that's why the refrigerator compartment isn't cooling.

The evap fan blows the cold air from the freezer compartment into the refrigerator compartment to cool it down.

The freezer compartment is cold because that's where the evaporator unit is located. The evap unit is where the cold temp is generated, due to the refrigerant gas that is being pumped through it by the compressor.

Not sure with your model as I can't find the wiring diagram for it, but if the compressor motor is running, try manually operating the door switch (with door open) to see if the light turns on and the fan turns off.

If the fan isn't running when you have operated the door switch i.e. light is off, try pressing the switch a few times just in case it's a faulty switch.

With most refrigerators the evap fan runs as long as the compressor motor is running, however the evap fan is turned off, when the door is opened because you don't want any cold air being blown out from the compartment. The compressor continues to run when the door is open. The fan will restart when the door is closed.

The only way the controls know that a door is open is because the door switch is released by the door being open. This switch is also used to turn the light in the compartment on and off

Thanks for your response, @Jayeff. It turns out the freezer fan isn't working, it was humming for quite a while, and that's when we noticed the excessive frosting issue kicking in. Appreciate the video link! I'll go ahead and replace the fan and keep you posted on how it goes. Fred

Thanks, Jayeff and Bill, for your help. Here’s the update: I knew the evaporator fan wasn’t working, so when you guys mentioned to check it, I when ahead and ordered a replacement. When it arrived, I removed the icemaker and back panel, and surprisingly, the fan kicked on. But as soon as I let go, it stopped again. Turns out heavy frost around the blades was likely the issue. I wedged a ruler to keep the panel from touching the fan, and the fridge started cooling. All seemed fine, so I didn’t dig deeper. But now, the fridge isn’t cooling while the freezer still works no heavy frost or humming sound from fan. Last time, this same pattern ended with both sections failing. Any ideas for next steps?

The frost is not caused by the freezer freezing excessively, it is caused by water vapor.

Water vapor (warm air) gets into the freezer from a bad door seal or a door that isn't closing totally.

Carefully inspect for that.
