Hi,
Any pointer to help me repair my portable induction cooktop ? (TEFAL IR-2018)
Symptoms : suddenly cease to heat. No error message. When changing program / power level, the display flips between the previous program and the animation showing that the plate is supposed to heat.
So far I tested the usual suspects :
- Power supply
- IGBT --> not shorted (no functional test done though)
- Diode bridge
- Safety Relay
- Capacitors
- Some low power components around the IGBT driving stage.
- Thermistors (3 on the plate, one under the IGBT) looks ok.
Everything is ok. The device looks ok and is well engineered (european standards).
When powering on there is +320V. If I start to cook the voltage at the coil falls to zero (to be confirmed, I should measure again) and nothing else happens.
Without schematic it's hard for me to get other ideas
. Any advice ?
Thanks :-)
