Question about Thermador Refrigerators

1 Answer

Our 48" Thermador freezer/refrigerator started frosting at the top of the freezer. It is over 5 years old. After replacing the rubber liner to the door it still didn't fix it. Is there a fix ?

It is frosting at what is a seam in the lining of freezer and tech says it can't be fixed. Thermador is offering 50% off a replacement unit. Is there a fix for this?

Get a second opinion, but I would say thermador must think he’s right or they wouldn’t offer the 50% off.

SOURCE: motor runs, some ice at top level, but temp is at 50-60 degrees.

Defrost the freezer. Door being ajar allows moisture to build on the freezer coil and stops air circulation. In frost free units this condition should clear itself after about 8-12 hours max. Locating and advancing the timer by rotating the clutch head screw clockwise slowly until you hear one click. This will start the automatic defrost manually.

SOURCE: Frost problems on the two top drawers of the freezer

you can manually defrost the unit with a shop vac that has a attachment that will direct the outlet air to the problem but that is just a temporary fix, the main problem is that moist air is getting into the freezer either from the gasket or somewhere else. Try the dollar bill test on the gasket to see if its bad. This is how to do it,you take and put the money between the gasket and the refrigerator and close the door. If you can pull out the dollar real easy the it's time to replace the gaskets. if there's resistance from the gasket then they are ok. From there you can decide if you want to call out a service tech or attempt the repair your self. Thank you for using FixYa.

SOURCE: Amana tr25s5w top freezer refrigerator.

Their are a couple possibilities;

The door gasket was letting air into the freezer and the resuliting warm air will condensate and freeze and the resulting ice of the condensation has froze at the vents where the cool air enters and or returns from/into the fresh food compartment. the vents can be seen in the ceiling of the fresh food section and you would see ice build up in them. If thats the case turn off the entire unit and use a hair blow dryer to thaw and remove that icebuild up freeing the vents for proper air flow.

Secondly it could be a defrost problem BUT the vents are clear but the coil in the freezer is still blocked with frost,once again blocking proper air flow into the fresh food section. If the coil on back wall has frost on it but NOT between all spaces its the vents. IF entire freezer coil is blocked with frost and you cant see between the open spaces on the coil in freezer its a defrost problem.

Heres what to check if entire coil in freezer is on big frost block;
DEFROST HEATER ...remove back wall of freezer and you will see a black heater at the bottom of the coil thats frosted up,it looks similar to the bake element in your oven,or in some cases it is going to be a spiraled wires inside of a glass tube. To check it,use a multimeter set to the lowest ohms of resistiance setting and follow and find the wires at the top of that frosted coil,unplug/disconnect those wires and check for continuty with around 5-20 ohms of resistiance. If it has that amount of ohms the heater is good. If your meter display does not change or displays OL the defrost heater is broke and needs to be replaced

DEFROST TERMINATION THERMOSTAT... it's round and has 2 wires and clips to the top of that frosted up coil. IT MUST BE CHECKED WHEN COLD SO BEST TO DO WHEN FROST IS STILL BUILT UP. To check it disconnect the wires on it and check for ZERO ohms of resistiance. As with the heater if the meter display OL or doesnt change,it is the problem

DEFROST is hard to check for a semi unskilled person and if the heater or defrost t-stat check good its going to be the problem. It will NOT be in the freezer it could be on back wall or inside the control panel in the refrigerator section.

Good luck,
While these pictures are for a different brand ALL refrigerators are similar and may look some what different than your but will be similar enough to yours

In the freezer behind the false wall is an evaporator, surrounding this is a heater for defrost purposes. While inspecting this, look to see if the heater has made contact with the liner in any way, it is possible but rare the cal-rod heater has changed shape and made contact with the liner. So when the heater comes on during defrost it melts the liner giving off a chemical/burnt plastic smell. Best repair in this problem is to move or relocate the heater away from the liner, seal the liner with silicon and tape (a nylon tape), be sure to clean the heater also to prevent more smells. Good Luck

Sounds like a defrost failure.
Look on the back wall of the freezer from the inside.
If it is covered in ice your defrost system has failed.
Also check the fan motor in the freezer.
If it is not running it must be replaced.

The display will stay on normal for about 5 min and then give me a Er FF. What to do?

problem may be the main pcb or evaporator fan motor. this unit has several problems. if the model# starts with a 795 it was made by LG. the er ff code is caused most of the time from frost building up around fan motor. this can also be caused by freezer liner sagging at the top of freezer causing frost build up, sears has a service flash for this that is covered by the manufacture. service flash sf46-512. iwould call sears and find out if your model is on this service flash.

Fridge not cooling- top freezer frosting over

"Fan in freezer does not seem to be running"

This wiil cause it to frost up in the freezer and this fan is the only way to get cold air into the Fridge area.

Refigerator leaked water slightly then stoped cooling

Yes try to turn with a screw driver if possible. If it start working replace timer. If not it can be low on freon you would see frosting but no cooling.

New Refrigerator Past Warantee Not staying cold

is the fan in the freezer running? if not then the air cant circulate and nothing will cool properly. if is running, is there frost build up on the inside back wall of the freezer? if so you have a defrost problem. if no frost on the back and the fan is running, remove the back panel inside the freezer and make sure all of the silver coils have light frost on them. if only part of them are frosted get out your manual and look at the warranty section. then seal system may have a 5 year warranty. if it does then call sear for warranty service. if the coils only have partial frost and its not under a 5 year warranty buy a new frig. because repair will cost more than its worth
