What we repair
A freezer has to hold a steady low temperature, so a small fault can spoil food quickly. Most calls come down to a handful of problems, and a technician confirms the fault before any repair.
A failed defrost system, a blocked evaporator, a faulty fan, a dirty condenser coil, a temperature sensor or a sealed-system fault can all stop a freezer holding its temperature.
Frost on the walls or vents often points to a defrost fault, a door that does not seal or a door left open. A technician confirms the cause before any part is replaced.
Check the breaker and the outlet first. A dead display or unresponsive controls after a power cut or surge can also be a control board fault.
A worn or dirty gasket, a door that sits out of line or items blocking the door can let warm air in, which causes frost and a warm freezer.
A freezer that runs constantly, or makes a loud or unusual noise, can have an evaporator or condenser fan fault, a dirty coil or a cooling problem.
A door alarm, a temperature alarm or a code points to the system involved. Write it down before you reset anything, so a technician can trace it.
Keep the freezer door closed. A full freezer holds its temperature for about 48 hours (24 hours if half full), according to the USDA. Food that still has ice crystals or is at 40°F or below can usually be refrozen. When in doubt, throw it out.
Parts
A failed part is often the whole story, but which one depends on the diagnosis. We confirm the fault before recommending a repair.
Compressor and sealed-system faults are a larger decision. See repair or replace below.
Before you call
A few simple checks can rule out the easy causes. Do not remove panels or work on wiring or the sealed system yourself.
If the freezer is still not right after these checks, a technician can trace the fault. Call or book online and tell us what the freezer does.
Repair or replace
Often yes, when the fault is a single part such as a fan, sensor, heater, gasket or control. A Thermador freezer is a large built-in appliance, and replacing it can cost far more than the part.
The answer depends on how old the freezer is, what has failed and what the repair costs compared with replacing it. Prices vary with the fault and the part, so we do not publish one figure. Our freezer repair cost guide explains what drives it.
Models
Thermador freezers come in several forms. If you are not sure which one you have, call us with the model from the data plate and we will confirm we can service it.
How it works
From the first call to a working freezer, in three steps.
Tell us the model, what the freezer is doing, any alarm, error code or flashing light and how warm it is running. A photo of the data plate helps.
Our technician traces the fault, whether it is a fan, heater, sensor, gasket, control or cooling fault, and explains what is needed.
You get the diagnosis and the repair options, and the repair goes ahead once you agree.
