Hello,

A mechanical defrost timer controls the defrost cycle of the freezer. In older models, the timer runs continuously and roughly every six hours, cuts power to the cooling system and sends power to the defrost heater. In newer models the timer advances only while the compressor or defrost cycle is running - an improvement for efficiency. As the timer continues to advance, power to the heating element is cut and power is restored to the cooling system. If the timer does not advance, the appliance will be stuck either in defrost or refrigerate mode, resulting in, respectively, no cooling or frost build-up.


The defrost timer is usually found behind the front grill "toe kick" of the refrigerator. It may also be found behind a cover plate inside the refrigerator or freezer, in the temperature control console, or behind the refrigerator near the compressor.
To test whether the defrost timer is simply failing to advance, locate the advance screw and turn it clockwise until you hear it click. This advances it to the next mode. If it was cooling before, it is now in defrost mode. Simply wait about 35 minutes and check whether it has left defrost mode and has resumed cooling (listen for the compressor). If it does not advance, the timer motor is probably bad and the entire timer needs to be replaced. If it advances as it should, then you can follow the steps below to test the switch electrically.
The timer is usually held in place with one or more screws. Remove the screws and gently pull the timer out far enough to disconnect the wiring connector. The connector can be removed by firmly pulling and rocking it left and right. It is not necessary to note the position of the wires because the connector plug is keyed so that it can be replaced in only one way.

Take care.

Fridge warm, freezer has frost on back panel & is defrosting, fans work, just changed defrost thermostat, no air is moving from freezer side to fridge side, drain pan under fridge is dry


this fan needs to run when the compressor runs,check fan blade for being jammed by ice if you have this much ice on back wall as ice will stall motor,if no fan there will be no cool air to refrige compartment also the defrost drain tray will fill with water then freeze over which in turn floods the freezer floor and refrige compartments cause it cannot drain to the pan in the bottom

Hotpoint RZA30 Future Freezer keeps icing up. needs defrosting every month


freezer can over ice when not enough air is curculating to the back of the unit, if you have a very warm or hot kitchen the curculation on your freezer over ices the contence because of lack of air getting to the pump, the grinding noise could be the pump working overtime trying to gather air. also check the back where the tank is to made sure nothings been damaged ie - kinked in pipes.

Fridge not getting cold...but freezer is working


the fridge gets its cold air from the freezer fan blowing it through small air passages between the freezer and fridge. when you adjust the temperature in the fridge you are increasing/decreasing the amount of air being let into the fridge. Two common problems that could cause the freezer to freeze but not the fridge getting cool is the freezer coil is frooze like a ice cube blocking the air going to the fridge or freezer fan is not working could be bad or froze up due to too much ice. If fan works after manually defrosting problem could be in the auto defrost mechanism. If fan don't work after manual defrost replace fan. Manual defrost by putting a pot of very hot water in freezer with door closed change water foten until defrosted.

Bottom frezzer is working but fridge is not blowing cold air


Refrigerator gets cold air from freezer compartment. Either the air flow is blocked by food items or ice, or the recirculating fan is not working.

The most common failure is that the freezer coils get all iced up becuase the defroster timer, defroster thermostat, or heater has stopped working.

When it's running, you should feel cold air blowing out of the vents that are in the fridge, otherwise, the 'air tower' (air vent) is blocked with ice.

If you manually defrost the whole thing, and it runs fine for a day or so, then it's not defrosting properly. If you manually turn the defroster timer, and you don't hear the scorching/hissing/gurgling of the defroster working, then that would confirm a fault in the defroster circuits.

Based on the following thread, it's probably a bad defrost thermostat.

Warm fridge cold freezer


Hi,advance thermostat setting, to get colder , it's possible you got defrost problem, is there excessive ice building inside back of freezer? to determine if you have a defrost problem, unplug ref. for about an hour,let it defrost, let all ice melt away, it's better to remove your produce, keep doors open to speed up defrosting, after defrosting and cleaning plug back your ref, and let it work for another hour, and check result, if it's o/k, put back your produce, let me know, during hot summer months, regular use (opening) of ref, could cause excessive ice build-up evap. if after defrosting and cleaning ref. work good for 3 to 4 days, but start doing the same thing, let me know, it means you got a defrost problem. also check your thermostat, but first defrost and clean it, that could just be your problem. good luck.

Freezer works, fridge doesn't cool


Probably excessive ice in the condensor. Likely defrost thermostat or defrost heater problem.

What happens is excessive ice keeps airflow from the refrigerator part of the unit.

Frigidiare PLHS39EESS9 Ice build up in bottom of Freezer


I had the same problem with my Jenn-air side-by-side

Your freezer has a defrost cycle and when the freezer temp is set too cold, your drainage pan and tube freezes up (behind the back panels in the freezer) and when that gets full it spills over too the bottom of the fridge and keeps building up until you notice.
  • Un-plug fridge and put your food in coolers or another fridge.
  • Defrost the freezer, remove the ice from the bottom.
  • Remove the back panel/s (in the freezer).
  • Check the drainage pan. If it is iced up, you'll have to carefully remove the ice and check the drainage hole.
  • If the hole is iced up, so is the first 1-2 inches of the plastic tube leading to the main drainage pan behind and under the fridge.
  • You can use a hair drier to speed up defrost.
  • To defrost the hole and tube I used round ended metal (nut pics or beater attachment ends- avoid sharp objects) heated up in boiling water and gently forced down into the hole and tube until defrosted.
  • Check flow(by pouring warm water) down and looking behind and under fridge(with flashlight) to see if flowing into main drainage pan.
  • Turn up your freezer temp and check with a thermometer. Your freezer temp was probably set too cold
Mine is going on 5 months with no problem. If this continues, it might be the defroster.
Good Luck!

Fridge too warm


I had a similar problem several months ago.

1) Top freezer compartment is getting TOO cold. The ice gets so thick, it blocks the channels of cool air from the freezer down to the fridge compartment (hence fridge too warm)
SOLUTION: Turn fridge/freezer off to fully defrost, then turn back on.
NB: This might only be a temporary fix, and you will find in a few months time the same thing happens?
2) In my case, I required a replacement of the "controller" board which fixed the defrosting problem of my freezer compartment. 
Good luck.
