The whirlpool side by side needed upgrade of control components William M. • Sunnyside , WA • February 06, 2017
The 20 year old unit still serves us well, looks good and has been kept in good repair. The condenser fan had stopped so I removed, cleaned and oiled that motor. The decision was made to make an upgrade to the evaporator motor and control units so that the appliance could reasonably be expected to have extended service life. The Ice maker module had been replaced 7 years ago. I ordered the parts and have made the upgrade for temperature controller and the defrost control. If you are in a...

Frost on the liner at the lower back and warm temp Catherine P. • Southampton , PA • August 05, 2014
Replaced the defrost timer. It was not located where the parts explode suggested in the thermostat control box which is located in the upper right corner of the liner. It was in fact outside the freezer compartment on the back lower left support (when looking at the back of the freezer). It is secured with 2 sheet metal screws with a 1/4 hex head. The manual override dial is visible through a punched hole in that support. Just remove the 2 screws, disconnect the electrical connector. Then...

I had no cooling in the upper ( not freezer) section of my frige Alexander M. • Gloucester , MA • August 23, 2015
I had had the same problem 4 or 5 years ago and spent close to $200 to repair it.
I did have the slip from that repair with part #'s so I went ahead and ordered a defrost timer and thermostat.
You-tube had plenty of videos on replacing those parts and even before they arrived I was able to add a switch and bypass the broken thermostat and start a cycle manually with the timer. (which it seems was was still functional).
Between that and cycling some ice packs up from the still working...

The refrigerator was operating in an unusual manner. The freezer would get abnormally cold even when set at the warmest temp on the dial. Then the refrigeration area was too warm. Greg T. • Boulder , MT • March 23, 2014
I took the bottom tray out of the freezer and found the coils iced up severely. I was reasonably sure the defrost timer was the problem and your tech said that was a good possibility. Ordered and replaced timer. (15 minutes) Problem fixed!!! Saved purchasing a new fridge at big bucks. We live over 40 miles from a service center so the cost of having a tech come out is astronomical. Thanks!!!

This defrost timer cam replaces the plastic cam on a mechanical defrost timer. It restores the timer's changeover between cooling and defrost, helping prevent frost buildup on the evaporator and temperature swings inside the refrigerator.
- Mounts on the timer shaft to actuate the internal switch between cooling and defrost
- Helps resolve issues like heavy frost on the evaporator, warm fresh food section, or a unit stuck in defrost/run
- Corrects timer advancement problems caused by a stripped, cracked, or missing cam
- Typically installed with the defrost timer in the control housing or rear service area
What's included: 1 defrost timer cam Install notes:
- Disconnect power before servicing
- Access the defrost timer and note the original cam's orientation for reference
- Remove any retainer, pull the old cam straight off, and press the new cam fully onto the shaft without forcing
- Reassemble, then manually advance the timer to confirm it switches modes before restoring power

Erratic cooling ice buildup in freezer Donald M. • Stover , MO • March 13, 2015
I replaced the Thermostat and Defrost Timer. It was a fairly easy repair other than removing the old Defrost Timer. The way the manufacturer, in this case, Amana, mounts that unit with "clips" is just poor design and engineering. It is virtually impossible to get the timer out without damaging the mounts. I had to do some creative rework to mount the new timer.
After 2 days, the fridge appears to be working properly with these new parts.
The new parts were shipped Very Fast...APP is...

The refrigerator section was not staying cold as before and the noise was louder than normal Stephen S. • Flagstaff , AZ • July 11, 2015
At first, I suspected the evaporator fan motor was going bad, but when I went in to check it out, I found the evaporator coils totally frozen up; the fan was cavitating. I defrosted the coils completely and checked everything out. By process of elimination the Defrost timer had to be the culprit. I unplugged the timer and sure enough, the motor winding was open. Replacing the defrost timer fixed my problem. Troubleshooting (using the information available on your web site) took a little...

Genuine Whirlpool part
By: Whirlpool
Part Number: WP2162045
This mechanical defrost timer advances the refrigerator's defrost cycle so the evaporator periodically melts accumulated frost. It helps restore normal cooling cycles and prevents excessive frost buildup for more reliable refrigerator performance. What it does:
- Advances the appliance between cooling and defrost modes on a timed schedule
- Stops the compressor during defrost so accumulated ice on the evaporator can melt
- Commonly replaced when heavy frost builds on the evaporator or the fridge/freezer cycles abnormally
- Can address symptoms such as excessive frost, reduced cooling, or continuous compressor operation
What's included: One defrost timer (single unit) Install notes:
- Disconnect power to the appliance before starting any repair
- Access the timer through the back or control area per your model's service instructions
- Note wire locations or take a photo before disconnecting to ensure correct reassembly
