Typical defrost set up 8 times a day (24hrs)
duration about 20mins for the size you have described.
defrost stop temp should be 20 C
recovery time about 10 mins

so pls consult manuals and rest parameters.

There is a light in my freezer. but, it doesn't get cold


Hello;

My name is Peter. I am a retired field service refrigeration technician.

You are locked into the defrost mode. This is where every 8-10 hours your unit will completely shut down except for the lights. At this time your defrost heater turns on for 20-30 minutes to defrost the evaporator (Cooling) coils in your freezer.


You can manually turn your unit back on, until you get a new defrost timer. If you have a up right freezer your defrost timer is in the lower back. It is mounted on a metal plate.

With a flat head screw driver turn the stem slowly one click at a time until your unit turns on. Once a day repeat this process to put your unit back into defrost until the timer is replaced.

If you have a top freezer the defrost timer is located on the top of the fresh food section on the left. Do the same thing. The cost of the timer is about $30.00.

Send me your model number located on the side front wall of your fresh food section and I will proved you with the part number and walk you through the repair.

sounds like a bad defrost terminator or timer wired wrong. won't make temp as the evap is not clear of ice/frost build up. check your wiring diagram for location and operation of terminator.

Upright freezer orange and red light on but green light off can you advise? Frigidaire freezer.


Draw fan has failed, temp unreachable over the past cycle of 24hrs, turn your unit off for 24hrs and defrost it, restart and should work fine for a few days, if so, replace fan and defrost element only. Call service tech for this unless you are clued in on this work, not that costly.

Why has my freezer stoped freezing. it is cold inside and the red warning light is on


The defrost heat element has failed or the fan unit has failed, either way it is easly diognosed and not too costly if you pick the right repairer.
If you turn the unit off for 2 days and defrost it total, then turn it back on, should work fine for 4-5 days then return to problem again, confirming my report, you can then tell repairer you are not stupid and hence, not get ripped off.....Russ

The temperature keeps on rising. everything inside is melting. does not freeze anything. fan and light is working.


Turn it off, defrost it for a couple of days """""with the door open""""", restart it with door closed and see if it starts freezing again after about 2-3 hours, if so, then the draw unit works, that indicates the defrost cycle needs to be reset or one of the defrost elements has failed causing the rest no to do anything. Any probs call me on 08 9523 0552 Russ

There is definately a ground fault in this unit. Also according to the service manual this is an "Electronic Defrost Control" similar to an "
Adaptive Defrost Control" which determins the defrost initiation by the amount of run time. You cannot set this yourself.

Defroster get red hot


Kenmore Frostless Upright freezer model# 23971. The alarm sounded, all contents in freezer is frozen solid. We turned the alarm off, but the red light continues to blink. How do you reset the alarm and stop the red light from flashing? It has been 3 days now and every time we have check to see if the contents has started to defrost, there is no signs of defrosting, everything inside of the freezer remains frozen solid.

Freezer defrost cycle


If the defrost timer sticks in the defrost mode,yes. Normal defrost time is 30 minutes or less depending upon which timer is installed.
If it happens again,locate the defrost timer and turn the dial manually to see if the compressor comes back on. If so,replace the timer.
It is probably on the rear near the compressor. Some are under the front behind the dust guard.

Whirlpool AFB126/H/AL Freezer - Defrosting & Refrosting


Hi. I am Kelly and welcome to FixYa. Here is the real question..... Is the food staying frozen?

Freezers usually defrost 3 times a day (8 hr intervals) Some as often as 4 times a day. The freezer use concept is that it is not opened more than 3 times a day. (Yes there will be more times than that any given week)

Having said all of that.... some things to look at.

1. Check the door seal for any signs of tears... grease... collapse...

2. Make sure there are no gaps in the door or between the closed door and the seal.

3. Many people don't check this one... but make sure it is level. An un-level freezer can cause the door seal not to function correctly.

Now if your saying that the food is actually defrosting... then there are a few other things that can cause that.

A. Sticking / defective Defrost timer

B. Defrost element is not heating and the freezer goes through a VERY long defrost cycle as the contents have to reach 60 Deg F for the 60 Deg bi-metal thermostat to close and advance the defrost timer to start the compressor.

C. Intermittent operation of the 60 Deg thermostat

I hope this clears things up a bit for you.

Thanks for using FixYa.

Kelly
