Cooktop power module replacement: cost and what affects it
The power module is among the priciest parts in the appliance. The cost depends on the model and on whether the entire board has to be changed or only separate parts on it (transistors, triacs). See the table for prices.
| Service | Price |
|---|---|
| Burner / heating zone replacement (electric cooktop) | 300–400 zł |
| Relay / sensor replacement (electric cooktop) | 300–400 zł |
| Glass-ceramic surface replacement (electric cooktop) | 300–450 zł |
| Power module replacement (electric cooktop) | 450–600 zł |
| Electronics repair (electric cooktop) | 250–550 zł |
Indicative prices. Ranges for a typical scope. Fixings included, materials separate. Minimum order 300 zł.

How it works
- You explain what is happening.
- The technician checks the model.
- Breaker switched off.
- The cooktop is taken out and the power module is reached.
- The board is tested — transistors, triacs, diodes, and fuses are checked.
- Either a component-level repair is done or the full module is replaced.
- All burners are tested.
Mistakes
- Ordering a complete board when a single transistor was enough.
- DIY soldering on a power board: high current, and one mistake can mean fire.
- Ignoring a breaker that trips — that is protection doing its job, not a glitch.
- Skipping terminal checks: melted connectors will damage the new module as well.

Case from Warsaw
Client in Targówek: Bosch cooktop stopped after a thunderstorm — indicators were on, but the burners stayed cold. On site they found a blown triac on the power module, a voltage spike had damaged the semiconductor. Tradespeople changed the triac and a protection varistor that had failed too. All burners back working. It was a component-level repair, much cheaper than fitting a new board. The job took around 1.5 hours. Tip: if your area gets power surges, install a varistor or surge protector on the cooktop’s circuit.
FAQ
What is a power module?
A board with power semiconductors that sends electricity to the burners.
Always full replacement?
No: in many cases component-level repair can be done and costs less.
Why does it fail?
Power surges, overheating, and normal semiconductor wear.
DIY?
No: up to 32A, 220–380V.
Time?
1–2 hours.
Brings module?
Yes, if the model is known.
Brands?
Bosch, Siemens, Electrolux, Samsung, Beko, Amica.
Breaker trips?
Often it is the module, but it may also be a heating element.
Surge protection?
Install a varistor or surge protector on the cooktop line.
