Hello, your unit should go through the harvest cycle every 90 minutes if your temperatures in the freezer section are between 0 to -5°. Make sure you check for the proper amount of water into the ice maker. Should have about a half of an inch of water evenly across the bottom of the tray.

Hello
Here is all of the information we have on this product. I also have a senior technician that will be adding more to this post soon.

Hello, Your bake and broil relays are working correctly. They will show voltage when off. When on, as power passes through you will lose that voltage reading. If both bake and broil are out without an error code, I suspect it may be your oven safety thermostat. Part # 318578509. I have attached a link to SearsPartsDirect so you can see it in the parts breakdown. You can check the thermostat with a multimeter set to ohms and it should have continuity across the terminals (with wires unplugged). PLEASE be sure power is off before any testing!

Hello
I have provided the tech. sheet and parts breakdown to help you diagnose the issue.

Hi. It does sound like a bad speed sensor since you’re not getting a reading on the old vs a reading on the new. I have had to replace a few of these. I’m not sure what the speed sensor should test. I have attached the service manual for you. I would check error codes and follow the testing accordingly. They may show how to test the sensor in the manual.

Hello
Go to the link below to page #20 in the service manual link. This will give you an exact flow chart on how to diagnose and repair your issue for Dryer Heating.

Hello
There are a few possibilities of your specific symptom. Most common is an evaporator motor not running or defective. To do a complete diagnostic check go to the Service Manual link below and go to page #43 Section 8-3.

Hello
The 4- blinking lights is a Motor Locked / Over RPM. Go to page #102 in the link below for diagnostic steps. The control board and compressor diagnostics are on this sheet.

Hello
If the compressor was replaced recently, I would make sure it has a proper refrigerant charge. If it does a few more things can cause fluctuating temperatures.
1) Make sure the doors are closing properly and have good seals.
2) Make sure the interior lights are not staying on when the door is closed. You can have a bad door switch or sometimes a hinge cam riser that will not close the door switch and leave the light on.
3) Check for stored error codes in section 6-1 in the service manual link below. Follow troubleshooting guide on additional diagnostics.

Hi. We have found the drain pumps to be taking out the board on these units. Ran into the same thing multiple times . Put a board on and instantly fried it. One actually had a flame. Check the drain pump. It should be around 12-14 ohms I believe. The bad ones I’ve tested were reading at about 1 ohm.

Hello the P5 error

            If the control does not detect a valid water level sensor input for 30 seconds, or if the Max (Overflow) Fill Level in the control is set to 0 while in Run Mode, Factory Test Mode, or Overflow Mode, the control will enter Machine Error Mode. Check harness from user control to pressure sensor for damage and replace if necessary. Replace pressure sensor or user control if error persists. The control will first drain for 30 seconds to get out any water and then unlock the door. Unpower to clear error. See complete service manual link below.

Hello
You say there is a ice build up on the right side. Does the rest of the Evaporator have an even cold LIGHT frost pattern ? If it has a light cold frost pattern then I would replaced the Bimetal thermostat . It is located on the upper left side of the evaporator with two wires going to it. To see a picture of the bimetal go to page #43 in the link below section 4-3. Replace it and shut the unit down for 24 hours to defrost the ice with the the doors open.

Or does the rest of the evaporator have no frost and feel wet? This means you have a sealed system issue. Either a deflective compressor or a leak in the system. Either way its not worth the repair unless its under an extended warranty.

I would start with the service pointer . The thermistor in the service pointer needs to be tight on the refrigerant line and in the correct location. Follow the instructions in the service pointer. That will cause it to freeze up.

Hello Kris
There is a possibility of frost build up on your evaporator. I would look at the evaporator coil to see if there is any frost on it. If there is, the evaporator fan motor blade could be hitting the frost build up and causing noise. If that is happening order the part number kit below. See the directions below for the Service Pointer ( Frost on Freezer evaporator ) . If the blade is not hitting frost, you could have a bad blade that is stripped or a defective evaporator motor.

Hello
The F0 E3 code is A Overload error. This Fault code is displayed when the main control detects a load size that exceeds the washer’s capacity OR basket cannot be turned.
This may signify:
• Load size exceeds washer capacity. Remove excess laundry, then restart the cycle.
• Mechanical friction on drive mechanism or basket (items stuck between basket and tub).

Can you please double check your model number Mvmb765fw3. It does not come up in our system.
