What is the standard defrost timer control setting

our freezer is set to defrost every 8 hours for 15 min. this seem to do the trick. we have a true t-49f reach in freezer. try this setting and see if it works for your situation.

Frigidaire equips most of its refrigerator models with automatic defrosting capabilities. This means that owners don't have to set a calendar reminder to manually defrost. The internal automatic defrost control and timing mechanism is placed at the bottom of most Frigidaire refrigerators, next to the stationary pan that captures water - even the defrosted meltwater is automatically evaporated. You might be confused about how the defrost timer works, thinking it is broken. Frigidaire understood this might be an issue for some owners and suggests double-checking the defroster for normal operation because it may not be malfunctioning at all.

Hello,

Depending on model it have a defrsot timer or perhaps a electronic defrost control but they usually will be located in the control panel if you have a knob used to set the tempature and if it has a digital display that you set the temp. by pushing the button on the front it will have a defrsot control and thats not so easy to put into defrost as the timer is.

Please reply with exact model number as found on the label in the fresh food compartment and i will tell you if you have a defrost timer or electronic control

Hi Guys, I tested fan removed(to 240vlts) neg- pos to wires+earth to mount bracket, and found to be working, reinstalled and found power - active to both wires??fan cut out (defrost mode)activated by timer control, my timer control ( bottom rear near motor) has a knob, so i turned it and fan started,continous turning knob ran thru all cycles defrost,fan start, etc: obviously timer control was faulty, To save frozen goods , i set control to run and installed a power point timer to cycle freezer till new switch arrives, taking the place of faulty controller...

Hello there:
first make sure that the back of the unit is clear of any dirt or obstructions
also make sure that the food is not stacked up so high that the air cannot circulate also you may want to check the temperature setting if the unit does not respond to a lower setting your refrigerant level may be low or than you will have to have the temperature controle thermistor serviced or replaced

If the evaporator coils behind the back panel of the freezer are icing up because of auto defrost failure that will stop the circulation of cold air and eventually affect the freezer too.

check defrost timer, defrost heater, defrost thermostat. In most newer models the timer has been replaced by an electronic control board. If the heater and thermostat are ok it’ll be the control.

You can turn the defrost timer till it clicks and everything shuts down. The heater should now come on. If it does, replace the timer. If it doesn't, check the heater and defrost thermostat. Turn the timer again till everything starts back up to end the defrost cycle.

You can use a hairdryer to speed it up but you need to fix the defrost sytem.

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

Three things could be the problem. Most likely would be the defrost thermostat which clips onto the evaporator behind the panel in the freezer. 2nd would be the timer or control board (will have one or the other). 3rd would be a bad defrost heater. Alot of times the def. therm. will show obvious sign of being bad by the cap on top popped open. You can check resistance on the heater. Any resistance at all on the heater means it is good. If it has a standard timer turn it clockwise until it clicks. This is putting it into defrost. If the heater comes on the timer is bad. If it has a control board you would unplug the unit then unplug the power supply to the board and jump line 1 to the wire going to the heater. While unplugged from the board and jumped, plug the freezer back in. If the heater comes on then the board is bad. If you are not sure how to test replace the def. thermostat, which is the cheapest part and see what happens. Note: When conducting the test for the timer or board the def. therm. must be freezing so don't defrost first! Hope this helps.
