# Bosch control board replacement cost

### The diagnosis most often guessed

A control board explains everything, which is precisely why it gets blamed for everything. A good share of the appliances we see with a “board problem” have a sensor, a harness, a switch or a supply problem instead — and those are a fraction of the cost.

### Storm season

Boards fail here in clusters after outages, in two versions. One is an appliance that came back confused and clears with five minutes genuinely off at the breaker. The other is real surge damage. There is no way to tell them apart without trying the free one first, and we always do.

### Where the figures sit

Published ranges put control board replacement at roughly $200–$500 depending on the appliance, with the part alone between $130 and $400. On an entry-series machine that can approach what the appliance is worth, and when it does you will hear so on the visit rather than after the invoice.

What moves this figure

Published range $200–$500 across appliances

Power and harness measured before anything is ordered

Several boards need configuring to the model after fitting

Which appliance

A dishwasher board and a wall oven board are different parts at different prices, and an induction generator module is its own conversation entirely.

Whether it is actually the board

A sensor reading nonsense makes a healthy board behave like a broken one. This is the repair where the diagnostic most obviously pays for itself.

Configuration after fitting

Several boards across this range have to be told what appliance they are in. That step is part of the job and part of the figure.
