Excessive Frost in the Freezer on Top Mount
Freezer compartment demonstrates excessive frost buildup.
Prolonged frosting may result in warming of the fresh
food compartment. The following conditions can cause
or contribute to excessive frost in the freezer:
• Excessive infiltration of warm, moist air due to
poor door seal.
• Poor function of the defrost system.
• Infiltration of warm, moist air through the drain
tube or ice maker fill tube opening.
• Inefficient dehumidification of air due to bypass of
air around the evaporator coil.
Symptoms: Frost build-up in the freezer
Warm fresh food compartment

This is an old unit and informational resources for this model are very limited. I did manage to attach a tech wiring diagram with timer chart and the complete job aid. Testing point and values can be found on these attachments with no further information available. Good luck.

Hello
I have attached a technician diagnostic sheet and a Job Aid. I did not see the F14 codelisted for your specific model.

I have found one resource online about the F14 Error :
** F14 showed up once, range is 4 years old. When I unplugged, the cord was noticeably warm to touch. F14 is a memory corruption on the Clock Module . Replacing the module is your only fix. This is only an online post. I would run the diagnostics to confirm.

See the complete technician diagnostics link below.
To invoke the Diagnostics Cycle, perform the following key presses in less than 6 seconds while in standby:
Heated Dry ➙ Normal ➙ Heated Dry ➙ Normal Alternative entry method if user interface is not functional: Unplug thermistor or OWI sensor 2 times while user interface is unplugged (no IDsor keys present).

• To rapid advance one interval at a time, press the Start/Resume key.
• Invoking Service Diagnostics clears all status and last ran information from memory and restores defaults; It also forces the next cycle to be a sensor calibration cycle.
  Calibration cycles begin with a “sensor check” to determine whether the dishwasher has an OWI soil sensor or not. If the control detects an OWI, it forces two rinses to occur prior to Final Rinse (to assure clear water), then calibrates the OWI during the final rinse.
