Kenmore model 59650009100 freezer settings do not stay, and a symbol with an exclamation point comes on, freezer starts to defrost.

Disconnect the defrost element and check with a multimeter for continuity. If there is no continuity, the element has failed. If the element is good, check the connections.

There is usually a Defrost Timer, but this uses a Defrost Sensor. Put 'defrost' into the Parts Search.

For Control Board replacement, I always advise getting a service call due to cost and warranty.

How is the actual freezer temperature? Some of these will alarm because the defrost heater and defrost thermostat are defective and others will do this because the=>216979700 Refrigerator Electronic Control Board I need to be there to check out this one. User Control and Display Board 216979600

I would think first of the defrost termination thermostat malfunctioning.
This would vary the defrost time since it regulates the defrost time by temperature.
This is the most common failure in fridges next to start relays.
It is a two wire item in the freezer section which is clipped onto a tube. It senses
line temperature and turns off the defrost element when that temp is reached.
Should be located in the freezer section behind the back panel. Model and serial
number should be inside the refrigerator compartment, Part should be available
at an appliance parts store. Hope this helps.

Hello,

You can fix this, just follow the procedure given to enable get back your refrigerator going,

I hope this will help in solving the problem......

All refrigeration products have a defrost set point. Most residential units defrost about every six to eighteen hours. This process should take about 30 minutes to 1 hour. The temp goes up so high inside because there is a heating element in the coils to thaw any residual ice. The temp should not exceed about 45 degrees though. If it does the the compressor is signaled to come back on and start cooling again. This is perfectly alright. The time at higher temp is not enough to spoil the food. Hope this helps. Good luck.

Some freezer models feature a temperature
monitor that provides an audible
alarm. The temperature monitor alarm is
located near the temperature control

The alarm sounds if the temperature in
the freezer rises 10° F (12° C) or more
above normal for selected setting. Alarm
may sound if temperature control dial is
turned to a much colder setting or if a
large amount of unfrozen food is added at
one time. Alarm is controlled by a three
position switch



• 0 = OFF prevents alarm from sounding
when freezer is warm, such as during
initial start-up or defrosting.
• ✓ = TEST sounds alarm regardless of
temperature. Alarm system should be
tested at least once a month.
• 1 = ON is proper setting for normal
freezer use. Return switch to 1 after
defrosting.

If all is ideal maybe -10 an occationally -15 and this is F considerable coolder than -20C. ALSO fyi a chest freezer will stay at or below these temps better than an upright and especially a self defrosting model. Because a chest freezer you dont loose all the cold air when you open the door. TYhey are not made in auto matic defrost as far as I know (never have seen one but then I havent been looking for one either. An up right freezer can be manual defrost or automatic. but the cold air falls ouit every time the door is opened.

Please let em know if this helps you by giving me as high a mark as you can and thank you for using fixya.

good day,
hope this link below will solve your problem.

ref

is it possible the door has not been closed at some point?
If so they can build up with ice in the evaporator which the defrost system cannot handle....Try a manual defrost.
Depending on where the unit is installed high ambient temperature can drop the internal temp enough to set the alarm off though they will still freeze sufficiently

Where is the fast defrost button on Kenmore chest freezers?
