EP
Whirlpool Refrigerator
Severity: ModerateWhat Does This Error Mean?
The EP error on a Whirlpool refrigerator indicates a fault with the evaporator fan — specifically that the fan is not running or is not running at the correct speed. The evaporator fan circulates cold air from the evaporator coils throughout the fridge and freezer. Without it, temperatures will rise in both compartments.
Affected Models
- WRS325SDHZ
- WRF535SWHZ
- WRS571CIHZ
- WRB322DMBM
- Most Whirlpool side-by-side and French door models
Common Causes
- Ice buildup around the evaporator fan blades blocking them from spinning
- Evaporator fan motor has seized or burned out
- Wiring to the fan motor is loose or corroded
- Door switch that activates the fan on door close is faulty
- Control board not sending power to the evaporator fan circuit
How to Fix It
-
Remove all food from the freezer and fridge and place it in coolers.
You need to perform a manual defrost to melt any ice that may be blocking the fan.
-
Unplug the refrigerator and leave both doors open for 24–48 hours.
Place towels on the floor to soak up meltwater. Thoroughly melting the evaporator area is the goal.
-
Once fully defrosted, dry the inside of the freezer and evaporator area.
Leaving moisture behind causes it to refreeze quickly and the problem returns.
-
Plug the refrigerator back in and listen for the evaporator fan to start.
You should hear a quiet hum or gentle whoosh of air within a few minutes of powering on. Open the freezer door — you should feel cold air circulating.
-
If you cannot hear the fan running after an hour, the fan motor has likely failed.
A technician can access the motor by removing the freezer's back panel and test it with a multimeter.
When to Call a Professional
If a manual defrost does not clear EP, the fan motor needs testing with a multimeter. Replacing an evaporator fan motor requires removing the freezer back panel. Expect repair costs of $100–$200 for the motor and labor.
Frequently Asked Questions
How do I know if my Whirlpool refrigerator's evaporator fan is working?
Open the freezer door and listen. With the door open, the evaporator fan usually stops (controlled by a door switch). Close the door and press the door switch by hand if accessible — you should hear the fan kick on. No sound after 5 minutes indicates a fan problem.
Can a failed evaporator fan affect both my fridge and freezer?
Yes — the evaporator fan circulates cold air through both compartments. If it stops, you may notice the fridge warming up while the freezer stays somewhat cold (because cold air pools at the bottom). Both sections will eventually warm as the evaporator coils also ice over.
How long does it take to replace an evaporator fan motor?
A technician can typically replace an evaporator fan motor in 45–90 minutes. The job involves removing freezer shelves and the back panel to access the motor assembly. Parts are generally available and affordable — the motor itself usually costs $30–$80.
