Bertazzoni P304IX Cooktop Heats on Only One Side: Internal Problem

What Only One Side Works means

On legacy Bertazzoni induction cooktops such as the P304IX and P365IX, you switch the cooktop on and only one side heats. The official explanation is an internal problem with the unit, and the instruction is to contact a service agent. Owners notice that the zones on one half of the cooktop respond normally while the other half stays cold, no matter which pan or setting they try.

Common causes of Only One Side Works

An internal problem on the half of the cooktop that stays cold
A power circuit that feeds only one side
A supply issue that should be ruled out first at the breaker

✓ One safe check you can try

1. Check that the breaker for the cooktop is fully on. 2. Try a magnetic pan of proper size on a zone from each side. 3. Switch everything off and wait a minute before trying again. 4. If one side still stays cold, stop using the cooktop and call us.

! Why to stop there

A half-dead cooktop means a power circuit inside is not working, which cannot be fixed from outside.
Finding the cause needs testing at the terminals and board, with live voltage present.
We give a written price before any work, and the repair comes with a 30-day workmanship warranty.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

Only One Side WorksOnly One Side Works questions

Could it just be the pan?

Only if you tested one pan on one side. Put the same magnetic pan on a zone from each half. If one side heats it and the other does not, the cooktop has an internal problem.

Is it dangerous to use the working side?

It is not an immediate hazard, but we would rather you did not rely on a cooktop that is partly out. A supply problem could get worse, so a technician should check it soon.

Does a tripped breaker cause this?

A breaker that is off would normally leave the whole cooktop dead. Because one side works, look to the internal circuits that serve each half, which is where we start our testing.
