Re: upright freezer

Maytag's design flaw is a too small drain pipe for melted frost. The pipe keeps clogging up (partially melted frost can cause this) and the overflow water accumulates in the bottom of the freezer and then re-freezes.

Re: upright freezer

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.

RFA52 upright fridge freezer keeps frosting up.what is the 'normal' setting for the freezer 0 or 1?

Setting should be midrange. If the freezer is frosting on the back panel you have a defrost problem. The coils will be iced over and the unit will slow down on it's cooling. If there is frost you will need to deice the coils by removing the frezzer back wall panel and use a hair dryer to melt all of the ice. The problem causer of all this will be either the defrost timer, defrost t-stat or defrost heater. Good luck.

1999 Frigidaire Refrigerator

Check rear wall of freezer by feel for frost. Heavy, even frost indicates likely problem in the defrost system. Unplug unit. Defrost heater (in freezer behind rear wall panel), defrost thermostat (same area-must be checked at freezer temperature) or Defrost timer-located lower back outside of unit. Near compressor. Do continuity test on heater and defrost thermostat and if they show continuity (good), replace defrost timer. If not, replace the one that tests bad.

Defrost coils fully. Reassemble.

Please let me know if I have helped with comments and rating.

Refrigerator will work about 7-10 days after being defrosted until thick frost builds up again cutting off air flow to both compartments

Just defrosted my freezer and is akll frosted over

When you say it is frosted over, do you mean the interior of the freezer is frosted, or the evaporator coils?

A couple things to check for:

1. Is the door gasket making a good seal when you close the door? A good quick fix for a bad seal on the gasket is to rub a thin layer of Vaseline (the original jelly kind works best) on the rubber to help it stick and to fill any scratches that might be keeping it from sealing tightly.

2. Is the fan running on the inside of the freezer? The evaporator coil in the freezer needs a fan to blow air over the coils to keep them from freezing over. They don't run continuously, and on some units will turn off when the door is open, so try holding the door switch shut when you check.

3. Is the defrost cycle working? Frost-free freezers have a defrost cycle in which a small heater turns on to thaw any frost that has begun to form. To check the functionality of the heater and the defrost timer will probably require a visit from a technician... It would take a while to explain it here, but if check the first two and come up empty handed, post back. You will need a volt/ohm meter.

I would check the first two

You have a defrost parts issue.
Unplug the fridge. Remove the back freezer panel and check the defrost heater and defrost thermostat.

Ice build up in my frost free upright freezer

I looked at the BACK at the bottom underneath of my Sears Kenmore frost free upright freezer and what was causing the ice buildup was very simple. At the factory, the assembler looped the little hose too high and when the water went into the hose it could not get out due to being too high in one spot! An ice dam will form, blocking ALL water coming through
and freezing up any more water coming down giving you a HUGE wad of ice that is scary!!! I just removed the screw holding the loop that holds the hose and put a bit of warm water down the little hole on the INSIDE (Behind the grate) to melt the remaining ice in the tube.You need to take out 4 screws and remove the grate to see this. I could not believe that this was the problem! I haven't had any ice build up since.Now don't tear your freezer apart before you try this trying to fix the compressor, thermostat etc. It may be the only thing wrong with it!
