Were is the defrost timer


Delfield freezers have defrost in the control. It is a thermostat, defrost control, and other things all rolled into one device. Not adjustable in any way. check the manual for details. http://download.partstown.com/is-bin/intershop.static/WFS/Reedy-PartsTown-Site/-/en_US/manuals/6000XL%20SERIES_spm.pdf

Fan on freezer won't com on but freezes food on


Hi and welcome to FixYa, I am Kelly.
There are 12 midelos that fall under the model number you passed. I will cite EV171NYMQ05 as a reference model number via this link:
http://www.appliancepartspros.com/partsearch/model.aspx?model_id=5140769

The freezer fan should be on anytime the compressor is on. If there is an ice block built up on the evaporator coils it can lock the fan blade in place via the ice build up. Additionally... if the fan motor bearings are dry or coated with sludge this too can prevent the fan motor from operating. The fan motor is item 3 this link: http://www.appliancepartspros.com/partsearch/model.aspx?model_id=5140769&diagram_id=28174432#d28174432

Detail views:

To check the can motor all that is required is a simple continuity check across the 2 connector wires. You should read under 480 ohms.

If you discover that the fan blades are encased in ice... do a manual defrost: (be ready to tend to a water mess)
1. By first unplugging the unit and then removing the freezer contents.
2. Direct an external fan into the freezer compartment for just over 2 hours.
3. Make sure the compartement drain funnel is clear of obstructions. Item 11 this link: http://www.appliancepartspros.com/partsearch/model.aspx?model_id=5140769&diagram_id=28158051#d28158051

After the 2 hour manual defrost period plug in the unit and test to see if the fan motor is running.
If it is running you may have an automatic defrost problem causing the ice build up. On a freezer the ice build up will start again if there is an automatic defrost problem in 3 - 5 days. Until the automatic defrost problem is corrected you will end up doing the manual defrost routine described above everytime you have improper cooling problems.

Components that can cause the automatic defrosting problems are
1. The defrost timer item 7 this link: http://www.appliancepartspros.com/partsearch/model.aspx?model_id=5140769&diagram_id=28257341#d28257341 Because it is not cycling or stuck in one position.
2. The defrost bi-metal thermostat item 9 above link (stuck closed)
3. The defrost heating element item 5 above link. (open)
And of course internal wiring....

Check the fan motor for continuity... if you attempt to lubricate it which is very difficult on this fan motor make sure you use paraffin based "Turbine oil" and not a regular household or automotive oil. Using any other oil will cause the fan to stop working in as little as 30 days.

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.

Freeezer is only freezing around 26 degrees


Dirty condenser, condenser fan motor is not running, freezer overpacked, bad thermostat, evaporator ice build up and it blocks the air flow. evaporator fan motor is not running or sealed system problem.

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.

Freezer not defrosting


You got the right idea. your fridge have a deforst problem, and it can be cause by a number of items. 1. the timer, 2 the defrost temperature control. 3 the defrost element itself.
Before you use the hair dryer when there is ice forming in the back panel, try to turn the timer and see wheather you can set it to defrost cycle manually if you can then the timer need to be change. the 2 and 3 item is a bit more work for normal people to deal with, you better call in a serviceman and watch him how he handle it so you can try it yourself next time. God Bless
