Whirlpool ED5PHEXNT00 not freezing at all

Whirlpool ED5PHEXNT00 is not freezing at all, light are on, but thing are barely cool, not even cold. I run some multitestor test on the compressor, capacitor. They seems to be fine. But fridge is still not working properly

I check the evaporator coil, it’s not even cool. There is no oil residue, so I assume no leakage from the compressor. The compressor fan and evaporator fan are both running fine. I start to wonder if the compressor is working, I touch it, it doesn’t vibrate, it’s barely hot. I cannot fully distinguish if the noise I’m hearing is the fan blowing or the compressor noise.

Hi,

Check if the evaporator unit, behind a panel at the back inside the freezer compartment is icy cold. Access is through the door at the front of the compartment

If not then there is a problem with the sealed system e.g. a leak, a blockage or perhaps a faulty compressor. The sealed system comprises the compressor, condenser, evaporator, filter dryer and associated tubing.

Check for any oily residues on the condenser coils or on or below the compressor. There is a special oil mixed in with the refrigerant that is used to lubricate the compressor. If there is a leak then the refrigerant will escape to the air undetected but the oil may leave a trace.

The high and low pressures in the sealed system would need to be tested to know if there has been a leak or not. Depending on your location, you may need to use a licensed repairer to do this, to comply with the environmental regulations regarding the handling of refrigerant gases. Also they have the equipment necessary to check the pressures.

If the evaporator/evaporator fan is iced over then there is a defrost problem. This could be due to a faulty defrost heater, a faulty defrost bi-metal thermostat, a blocked drain tube from below the evap unit to the evap pan under the compartments near the compressor or maybe a faulty control board.

The evaporator fan will run as long as the compressor is running and the doors (both doors) are shut. The fan stops when a door is opened as you don’t want to blow any cold air out. Try manually operating the freezer door light switch to check if the fan operates. This will fool the control board into thinking that the doors are shut.

Here’s a link to the parts for the refrigerator. If you need to replace a faulty part, there are other suppliers online that may suit you better. Just search for ED5PHEXNT00 parts to get results.

Hopefully this is of some help.

You should be able to feel (touch) some vibrations from the motor if it was operating.

Strange that the condenser fan is operating as usually it is thermostatically controlled and only operates if the condenser coils need cooling down.

If the condenser is not also warm/hot then there is nothing being pumped through the sealed system.

If you disconnect the condenser fan and leave a door open then the only noise should be from the compressor as both fans will be stopped

Maybe check if there is voltage on the compressor terminals.

Be safety aware if you try this as it is AC voltage which can be lethal

Will try that. I'm thinking the capacitor or the relay is not sending enough juice to the compressor

@Jephte Check the data tag on the compressor. What is the FLA and the LRA? Use a meter to check microfarads on the capacitor. Check and see if the relay is allowing power to flow through when it should. If those check out, then use an amp clamp and check the amperage of the compressor while it (should) be running. Be sure to only check on ONE wire at a time. If you try and check 2 your reading will be wildly inaccurate. If no amps, and everything else is good, then your compressor might have an open winding which is not repairable. If the amps are fairly low, then you're likely out of refrigerant. I don't suspect a clogged refrigerant system, as that makes compressors get very noticeably hot. But I do suspect a refrigerant leak. And it could very well be somewhere you can't see. Not all refrigerant leaks show oil residue. Alot do, but not all. Especially with the small size of the refrigerant charge in a household fridge.

If you are pulling full LRA and then it stops, then either your capacitor is too weak to start it, relay isn't kicking on properly, or the internals have seized.

@brandon_k

I will do that thanks, I will report my findings
