So first thing you try is , perform, manual defrost reset procedure.---------
The manual defrost reset procedure is as follows : ----
First unplug the unit from main power outlet. Then empty whole unit completely. Then keep both the doors open. Wait for 24 hours. All the ice collected on the coils and in the freezer section will get melted. Clean the water from the sections. Then Connect the power cord of the unit to main power outlet after 24 hours/.Then set the temperature to normal in both fridge and freezer section. Then check,if same frost is getting collected, then its defrost problem,. If it's again building up ice that means the unit is not defrosting. It's starting the cooling procedure, and then while defrosting, it's not working. The defrost assembly consists of three main parts. The defrost thermostat, the defrost heater and defrost board. Any of the one is not functioning. When thermostat sense the maximum cooling, it triggers the defrost heater to start heating and this defrosts the ice collected on the coils and the system works. Both thermostat and heater are controlled by defrost board. First the thermostat and defrost heater to be checked, if both check ok by meter and visually, then its defrost board causing the problem. IN YOUR case, defrost thermostat is already got replaced, so ignore thermostat, but other two possibilities needs to be checked.----------You can get required parts from from online sites like: --- www.repairclinic.com or from searspartsdirect online site. --------- This should help.Thanks.Helpmech.
My
fridge is running but not cold enough: Start out with the easy
stuff first...make sure the lights go out when you close the door(s), make sure the doors
are closing properly and the gaskets are closing fully and are not torn or ripped. Check to make sure the evaporator
fan in the freezer is working, this fan blows the cold air around. If the fan is not
working, possible bad fan motor - check for power to
the f
The most common fridge "not cooling" problem
is a frost free failure. Remove the access panel in the freezer section to expose the
evaporator coils. If the coils in the freezer section get plugged up with frost, this frost will block the evaporator fan
motor from blowing the cold air around. The fan blade can also hit this frost and either
become noisy or stop altogether. Locating the defrost timer can be tricky....they are often hidden behind the back bottom corners of the
fridge at the bottom, in the last few years the timers have been located in the ceiling of the fresh food section, and some are behind the cold control cover. Once you locate the
defrost timer, slowly turn the screw likeknob
in the middle of the defrost timer with a straight screwdriver until the fridge shuts off.
You are now in defrost. If the defrost heater (s)
comes on now, replace the defrost timer and defrost thermostat. If the heater(s) does not
come on, you can continuity test the defrost heater
for continuity or test for 120 volts to the heater(s). If you have
no power to the defrost heater (s) you can also
bypass the defrost thermostat to see if the defrost heater will come on, jumper the wires together to bypass the defrost
thermostat. If the heater now comes on, replace the defrost timer and defrost thermostat.
If the heater itself is bad, defrost the fridge with a hair dryer, replace the defrost heater (s) and
defrost thermostat. If the defrost timer seems
"hot" to the touch or is noisy ( like a ticking or screeching noise )...replace
it.
