Just turn the defrost tmer clockwise to cause defrost or run conditions. If you bypass the defrost timer you will have problems like shorting of wiring or loss of the timed defrost. Why not replace the defrost timer if you know it is defective? What is the model number of your refrigerator? Thanks Sea Breeze

If this Amana has digital display at top in fridge more than likely the Jazzboard (control board) has failed. Check for votage at fan if you don't get any or some times if you do the Jazzboard can still have issues controling the evap.fan. I've found the Jazz board to go bad some times. Hit me back let me know. Jazz board is in the control box were the digital numbers light up.

SOURCE: Freezer coils freezing, fridge warm

You might want to check and make sure the interior fan is working above the evaporator coils. If the fan isn't working the air won't circulate over the evaporator and it will frost over very quickly, and also cold air won't be pushed into the fridge side.

The fan might turn off when the door is open, hold the door switch shut while you check it.

Not defrosting


First, locate the defrost timer which may hidden behindcorners of the fridge at the back bottom, in some models located in the ceilingof the fresh food section or behind the cold control cover. Once you locate thedefrost timer, slowly turn the screw in the middle of the defrost timer withstraight screwdriver until the fridge shuts off. Now it's in defrost. If thedefrost heater(s) starts, replace the defrost timer and defrost thermostat. Ifthe heater(s) does not start, unplug wire cord to check ohm test for continuityof heater. If continuity is there, plug cord wire which gives power 120volts(check specification) to heater. If heater no starts, bypass defrost thermostatby join the 2 wires in the defrost thermostat. If the heater now comes on, replacethe defrost timer and defrost thermostat. If the heater itself is bad, replaceit. Thanks and hope helpful.

The freezer retains frost and obstructes the fan.


Defrost cycling is poor.
Locating the defrost timer hiddenbehind the back bottom corners of the fridge at the bottom, in some units it's located in the ceiling of the fresh food section,and some behind the cold control cover. Once you locate the defrost timer,slowly turn the screw like wheel in the middle of the defrost timer with astraight screwdriver until the fridge shuts off. You are now in defrost. If thedefrost heater(s) comes on now, replace the defrost timer and defrostthermostat. If the heater(s) does not come on, you can ohm test the defrostheater for continuity or volt test for 120 volts to the heater(s). If you haveno power to the defrost heater(s) you can also bypass the defrost thermostat tosee if the defrost heater will come on, join the 2 wires together to bypass thedefrost thermostat. If the heater now comes on, replace the defrost timer anddefrost thermostat. If the heater itself is bad, defrost the fridge with a hairdryer, replace the defrost heater* and defrost thermostat. If the defrost timerseems "hot" to the touch or is noisy ( like a ticking or screechingnoise )...replace it. Once defrost cycling is cleared, you will get better cooling in fridge compartment also.

Freezer is freezing, but fridge temp ranges between 40 and 50 degrees, problem?


Greetings,
usually this is a defrost problem...See if there is ice building up on freezer back wall and if so, you will find the evaporator froze over. I would first make sure you see or hear the freezer fan motor coming on. A evap fan not coming on will cause a no cool problem in fresh food section.

If there is ice on the freezer coil. It needs to be defrosted and then we can find the problem. Once its defrosted..it will work good as new until it freezes over again..The most likely problem is defrost thermostat or heater or timer or electric defrost board...you need to know how to use a meter to check these. The defrost thermostat can be bypassed to check it. use your meter to check the heater..if good, and you bypassed the thermostat and nothing happened..Its most likely the defrost timer or board. If a manual timer..you can advance it to defrost and see if it comes on.

if its an electronic defrost board, sometimes you can get them into a defrost by pushing the light switch in 5 times within 10 seconds..there may be a tech sheet on the refrigerator showing this
please let me know if you need more help....Bruce

Hello,

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.

The fan blade can also hit this frost and either become noisy or stop altogether.

If the defrost heater(s) comes on now, replace the defrost timer and defrost thermostat.

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, join the 2 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* and defrost thermostat. If the defrost timer seems "hot" to the touch or is noisy ( like a ticking or screeching noise )...replace it.

*One new safety device added to refrigerators in the last few years has been a in-line fuse added to both sides of the defrost heater. If one of these fuses let's go, you must replace the whole defrost heater, as it comes as an assembly. If the defrost heater does not work, you should check for one of these fuses being open. Check it with a volt meter or ohm meter.
On a frost free refrigerator, the cooling coils should be in the freezer section. On a SxS style refrigerator the coils will be behind a cover on the back wall. On a freezer on top style the coils could be behind the back wall or under the freezer floor. Removing the cover and exposing the evaporator coils could be a valuable tool. Seeing what the cooling coils looks like may help split your not cooling problem. Totally covered coils with white snow is a frost free problem. and the rest are bare is an indication of a system problem. Example picture one, example picture two, example picture three. System problems may be a leak in the refrigeration tubing, an inefficient not 100% pumping compressor.

Hope this helps...

My Fridge is warm, but my freezer is working great


Hello,

Your first job is to locate the source of the problem. Consider each of the following:

* Gaskets - Make sure the gaskets/seals are not torn and are sealing properly.
* Evaporator fan – Make sure it is working. If it is now working you may have a problem with the fan motor. Check for power to the motor and also examine the fan switches around the door (not all fridges have these switches).
* Air damper – Sometimes the air damper will not open up to allow the cold air from the freezer part to blow into the fridge section.
* Condenser coils – Check to see that the condenser coils don’t have a dust build-up and that the condenser motor is working.
* Compressor – Make sure your compressor is working with on and off clicking noises.

Step 2 – Frost-Free Failure

This is the most common cooling problem in fridges. Expose the evaporator coils by accessing the panel in the freezer section. The coils in the freezer section can sometimes get clogged up with frost. This can stop the evaporator fan motor from blowing cold air around, or cause the fan to hit it and stop, or become noisy. The defrost timer can be a bit tricky to find but it is usually located behind the back bottom corners of the fridge, although they can sometimes be found in the ceiling of the fresh food section, or behind the cold control cover.
Step 3 – Find the Timer

When you find the timer, turn the wheel-like screw slowly with a screwdriver until the fridge shuts off. The refrigerator is now defrosting. If you find that the fridge starts now, you will need to replace the defrost thermostat and the defrost timer.
Step 4 – Volt Test

If the heaters do not come on, use a volt meter to ohm test the defrost heater or volt test for 120 volts to the heater. You can bypass the defrost thermostat if you haven’t got power to the defrost heater to check if the defrost heater will come on. To bypass the thermostat, join the two wires together. Replace the defrost thermostat and the defrost timer if the heater comes on now.

If there is a ticking or squealing noise in the defrost timer, or it seems hot to touch, replace it.

Many fridges have and inline fuse on both sides of the defrost heater. You will need to replace the whole heater if one of those fuses blows. Check these fuses with a volt meter if the defrost heater doesn’t work.

A quick check if you have a cooling problem is to inspect the evaporator coils. If there is a build up of white snow on the coils, this indicates a frost free problem; if there is balled ice on part of the coils with the rest bare, this indicates a system problem, like a problem with the pumping compressor.
hope this help.....

Would also appreciate if you could provide us the model number of your fridge so that if the above solution does not resolve your issue would look into the matter specific to your type of model.

I am sure this solution would help you to resolve the issue.
