We repair Thermador cooking and refrigeration in Johns Creek, with appointment timing confirmed at booking. Thermador spans a wide catalog, from the Pro Grand range that anchors a serious kitchen to Masterpiece wall ovens, the full-surface Freedom induction cooktop, and Freedom refrigerator and freezer columns. What ties them together for a technician is that most of the electronic units, ovens, induction, and refrigeration, report faults as F-codes, while the gas cooktops use the patented Star burner and its spark ignition. Our service focus extends across the Thermador line, we read those codes correctly instead of guessing, and parts needs and availability are confirmed after model-specific diagnosis. Diagnostic and travel fees, if applicable, are confirmed before the appointment and before repair approval. Written terms are provided with the repair.
Models We Service
Thermador uses different platforms across cooking and refrigeration, so the model and serial from the rating plate points us to the right part before we arrive.
Ranges & Rangetops
- Pro Grand ranges in 36, 48, and 60-inch widths, the flagship with Star burners and one or two electric ovens.
- Pro Harmony ranges, the flush-installation pro range sized for standard cabinet depth.
- Professional rangetops that drop above a wall oven, sharing the Star-burner ignition.
Ovens & Cooktops
- Masterpiece and Professional wall ovens, single and double, with convection and electronic controls.
- Freedom induction cooktops, the full-surface design that senses cookware anywhere on the glass.
- Gas and electric cooktops, including Star-burner gas models set into island counters.
Freedom Refrigeration Columns
- Freedom refrigerator and freezer columns, built-in flush-panel units run by electronic controls.
- Under-counter and wine-storage units in the Freedom lineup.
Give us the line and width and we will match the correct igniter, element, sensor, coil, or control before the visit.
Error & Fault Codes
Thermador does publish fault codes on its electronic ovens, induction cooktops, and refrigeration, in the GE-style F-code family. An F-code narrows the problem to an area, a sensor circuit, a stuck relay, a control that has overheated or lost communication, but it does not name the exact part. We read the code, then confirm the real failure with meter readings before replacing anything. The table below lists the Thermador codes and conditions we see most, what each points to, and what we check.
| Code | Meaning | What We Check |
|---|---|---|
| F1 / F7 family | Control board or keypad fault, often a stuck relay or shorted touch key | Test the relays and keypad, verify the ribbon and harness, and fit an OEM control only when the board is confirmed bad |
| F2 | Oven over-temperature detected by the control | Check the temperature sensor resistance and the relays that could be sticking closed, and confirm the cavity is not actually overheating |
| F3 / F4 | Oven temperature-sensor circuit open or shorted | Measure sensor resistance cold, inspect the sensor wiring and connector, and replace the sensor if it is out of range |
| F codes on Freedom induction | Coil, cooling-fan, or control fault on an induction zone | Test the affected coil and its cooling fan, verify cookware is induction-compatible, and replace the coil or control if it tests bad |
| F codes on Freedom columns | Refrigeration sensor, evaporator fan, or defrost fault | Read the sensor values, test the fans and defrost heater, clean the condenser, and confirm the control is commanding the right cycle |
| Door-lock or self-clean fault | Latch motor or lock switch not confirming a locked door during clean | Test the latch motor and its switches, and replace the latch assembly when it will not confirm the locked position |
| No code, oven off calibration | Calibration drift or an aging sensor the control has not flagged | Measure actual cavity temperature against setpoint, recalibrate, and replace the sensor or element only if the readings call for it |
Because F-code numbering varies by model generation, we always cross-check the code against the specific service data for your unit rather than assuming a single meaning.
Common Problems We Fix
These are the Thermador calls we handle most in Johns Creek. We read the code or inspect the burner first, then replace parts only after the fault is confirmed.
- Star burner clicks but will not light. A fouled or wet igniter, a misaligned cap, or grease bridging the electrode on the star-shaped burner.
- Oven throwing an F-code. Most often a sensor circuit or a stuck relay, narrowed by the code and confirmed with meter readings.
- Freedom induction zone not heating. Non-magnetic cookware, a failed coil or cooling fan, or a control fault.
- Oven off calibration. Baking that runs hot or cold, traced to a drifted sensor or calibration.
- Freedom column running warm or frosting. A refrigeration sensor, evaporator fan, or defrost fault, sometimes flagged by a code.
- Self-clean door will not lock. A latch motor or lock switch not confirming the locked position.
- Weak or yellow gas flame. Blocked Star-burner ports or a clogged orifice, cleaned and verified to a clean blue.
- Control or display faults. An unresponsive console traced to the board, keypad, or harness.
The most common mistake with a Thermador is treating the F-code as the answer and swapping the part it seems to name. A sensor code, for instance, can be the sensor, its wiring, or the control input that reads it. Replacing the wrong one leaves the code and costs you a part. We read the code to narrow the area, then confirm the actual failure with meter readings before anything is ordered, which is why Thermador repairs done right usually hold.
Maintenance & Guides
Keep the Star burners and caps clean. The star-shaped port pattern is easy to foul with boil-over, and a shifted cap is a frequent no-light cause. Wiping the caps and drip areas and reseating the caps squarely prevents most ignition calls. Our Thermador repair guide covers the range, oven, induction, and Freedom column families and when a symptom is worth a service call.
Note the exact code before you book. Writing down the F-code and what the appliance was doing when it appeared helps us arrive with the right part. To read the symptoms first, our guide to Thermador oven fault codes explains what the common F-codes point to, and the guide to Thermador Star burner ignition covers the no-light faults we see most.
