Question about Thermador Refrigerators
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.

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.

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.

replace the ptc overload on the compressor,they just unplug off the compressor after removing the spring clip that secures it to the compressor

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 CONTROL...it 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.
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
