True T72F defrost timer and lights not working?

You have done good work here young man. There is a relay or switch that is keeping the signal for being processed. I had the same similar problem with mine. At least your compressor is ok. Are you sure timer is wired back right.

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

Frigidaire freezer runs a lot. Located in garage. In summer runs almost non-stop. Currently outside temps are below 0 deg F and freezer still cyles frequently. Have replace the freezer tstat. Defrost coil does not ice up, defrost elemen is good, and can cause defrost tstat to open/close. Seems like defrost timer could be stuck in ON mode causing freezer to defrost every time defrost tstat closes and stop when defrost tstat opens, repeating this cycle continually. Food remains frozen. Is it logical defrost timer is the cause?

Yup, these timers have a tiny clock motor that can get lint on them, causing motor failure, should be simple replacement. Refrigerators in cold garages run more to regulate their temperature below 45 degrees.

Coldspot model: 106 725540 freezes sometimes

You can by pass it but I wouldn't. You may need to replace the t'stat on this. This controls pretty much everything. Depending on your model, the defrost cycle can be adjusted to shorter cycles. Bypassing it would eventually lead to ice build up and a real mess to follow .

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.

My defrost timer was replaced by a brand new one, two days ago -- the defrost light turns on for 1 minute, another few moments after, the green light turns back on again.. my temp wont go down and I am not low on charge

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.
