Thermador repair, the whole lineup
Thermador spreads across more product categories than almost any other premium brand, and each one fails in its own way. A Star-burner gas cooktop lives or dies on its spark module and infinite switches; a Freedom Induction cooktop is all sensors, coils and firmware; a Pro Grand or Masterpiece range combines burner ignition with oven relays and convection; and a Freedom refrigeration column is a sealed-system appliance that happens to wear a Thermador badge. We service all of them across Hayward, from Hayward Hills and Fairway Park down through Mt Eden, Cherryland and Southgate.
The thread that ties our work together is the same on every visit: read the appliance before touching parts. We pull the model and serial, reproduce the complaint, check the electrical and gas side, and read any stored fault codes. Then you get plain-English findings and a firm price. When a fix is the right call we install genuine OEM Thermador parts and follow manufacturer-recommended procedures; when an old unit is not worth it, we say so. Our technicians bring extensive hands-on experience with high-end cooking and refrigeration, not a one-size guess.

Thermador symptom — likely cause — what we do
The faults we see most often on Hayward Thermador appliances, and how we run each one down before quoting parts.
| Symptom | Likely cause | What we do |
|---|---|---|
| Star burner clicks but will not light | Spark module, igniter or clogged burner port | Test the module and igniter; clean or replace the failed part |
| ExtraLow / simmer will not hold low | Worn infinite switch or burner-cap seating | Verify the switch and flame; reset the simmer cycle to spec |
| Induction shows an F or E error code | Pan-detect sensor, cooling fan or coil/board fault | Read the code, test sensors and the fan before any board |
| Wall oven dead or stuck on a code | Control relay, door latch switch or main board | Prove the relay and switches electrically; board only if needed |
| Oven runs hot or cool vs the setting | Temperature sensor or convection element | Measure actual temp; replace the sensor or element, then recalibrate |
| Refrigeration column not cooling | Evaporator fan, defrost circuit or sealed system | Check airflow and defrost; prove sealed-system pressures with gauges |
Before you call: a few safe checks
These take a couple of minutes and need no tools. They often clear a false alarm — and when they do not, they help us arrive with the right part on the van.
- 1 Reseat the burner partsOn a Star cooktop, lift the grate, check that the burner cap sits flat and centered, and brush any food debris off the igniter. A misaligned cap is a common reason a burner will not light or simmer.
- 2 Clear the induction surfaceOn induction, wipe the glass dry and use a flat-bottomed, magnetic pan that covers the element. Many F-codes are really pan-detection, not a hardware failure.
- 3 Power-cycle the controlFor a wall oven stuck on a code, switch off the circuit breaker for a full minute, then restore it. A clean restart clears some transient lockups before a service visit.
- 4 Check the column airflowOn a refrigeration column, make sure the grille is not packed with dust and food is not blocking the interior vents. Blocked airflow mimics a cooling failure.
- 5 Note the model and codeRead the model and serial from the rating plate — inside the oven door, under a burner, or on the column cabinet wall — and write down any code shown.
- 6 Still wrong? Call usIf the symptom persists after these checks, stop and call (628) 336-1354. Running a faulty gas, induction or sealed-system appliance can turn a small repair into a bigger one.
Why a diagnosis-first approach saves you money
Thermador appliances reward careful diagnosis because the same complaint rarely has the same fix. A wall oven "control board" code is, more often than not, a $40 door-latch switch or a single relay — not the $600 board a blind swap would charge you for. A Star burner that will not simmer might need an infinite switch or might just need its cap reseated. An induction error code can be a cooling fan instead of the logic board. We prove the failure electrically before we name a part, which is how we keep repairs honest and keep you from paying for hardware that was never broken.
That same discipline carries the hard cases. When a Freedom refrigeration column is not cooling, we read airflow and the defrost circuit first, then put gauges on the sealed system only if the evidence points there. On older units we will lay out an honest repair-or-replace recommendation with the real numbers — no pressure either way. Every repair uses factory-certified Thermador parts, and the labor is backed for a full year.

Hayward Thermador repairs
A star-burner on the Thermador wouldn’t hold a low simmer and one element was dead. They diagnosed the spark module and a switch, no upsell. On time and respectful of the kitchen. The $89 came off once I approved the work.
The ExtraLow setting on our Thermador star-burner cooktop stopped holding a true simmer and one burner ran high. They traced it to the spark module and a switch, fitted genuine Thermador parts, and now the low end is gentle again. Diagnosis-first, no upsell, and the $89 came off the total.
Our Thermador induction cooktop kept throwing an error and shutting a zone off. They read the code, tested the board and the zone coil, and it was a sensor — not the whole board they could have sold me. Fixed and warrantied for a year. Came right out to Union City and respected the kitchen.
Frequently asked questions
Do you repair Thermador cooktops and ranges in Hayward?
Yes. We repair Thermador Star-burner gas cooktops, induction and Freedom Induction tops, and Pro Grand and Masterpiece ranges throughout Hayward, including Hayward Hills, Mt Eden, Cherryland, Fairway Park and Southgate. We diagnose ignition, simmer, error-code and oven-temperature faults first, then fix them with genuine OEM Thermador parts. The $89 service call is credited to the repair you approve.
Why will my Thermador Star burner not hold a low simmer?
On the Star-burner design, a weak ExtraLow simmer is usually a worn infinite switch, a burner cap that is not seated flat, or a spark module that keeps re-firing. It is rarely the whole cooktop. We verify the switch, check the flame pattern and cap seating, and reset the simmer cycle to factory spec so it holds a steady low without clicking.
What does an error code on a Thermador induction cooktop mean?
Most F or E codes on a Freedom Induction top are pan-detection or cooling-related, not a dead logic board. A non-magnetic or undersized pan, a dirty surface, or a failing cooling fan can all trigger a code. We read the specific code, test the sensors and fan, and only consider the board after the simpler causes are ruled out — which usually saves you a large parts bill.
My Thermador refrigeration column is not cooling — is that a big job?
Not always. A Freedom column that drifts warm is often an evaporator fan, a defrost-circuit fault, or blocked airflow — all moderate repairs. A true sealed-system or compressor issue is the expensive case, and we only go there after gauges and electrical readings prove it. We give you an honest repair-or-replace recommendation with real numbers before any major work.
Do you use genuine Thermador parts?
Yes. Every repair uses factory-certified, genuine OEM Thermador parts and manufacturer-recommended procedures, which keeps the fix durable and protects the appliance. We are an experienced, independent Thermador repair specialist — not the factory — and all of our labor is backed by a 365-day warranty.
How much does Thermador repair cost in Hayward?
Most cooktop and oven repairs land between $210 and $1,100 depending on the part — a simmer switch or igniter is at the low end, an oven control board higher. A refrigeration-column sealed-system repair is more. The $89 service call covers the full diagnosis and is credited to whatever repair you approve, so you only pay it if you decline the work.
How soon can you come out, and do you cover nearby cities?
We often book same- or next-day across Hayward and the surrounding East Bay, including Castro Valley, San Leandro, Union City, San Lorenzo and Fremont. Call (628) 336-1354 or book online and we will give you the next available window. Reading your model, serial and any error code before we arrive helps us bring the right Thermador part on the first trip.
