Good morning! The Amica PI6508TF induction hob (PBF4VI508FTB4) survived the explosion of capacitors in the supply module: 2x 2.2uF and 1x 1uF. To maintain symmetry, I replaced the others (1x 2.2uF and 3x 1uF) for new ones. The board fired, however, I3 and I4 fields do not work. A pot placed on the field causes "clicking" and flashing of the heating level digit (does not detect the pot). Works on fields 1 and 2. What I checked: The field sensors are functional and have not moved. No visible damage to the power module or power fields. GSIB 2060: one has between + and - 90K, and the other over 150K GBG032 only since the I3 field has a voltage drop between the foot 1 and 3: 870mV using a semiconductor connector multimeter. The others have an opening on these legs.
I have no ideas. I am asking for advice on how to resuscitate a record. Measurements were made without desoldering elements.
Cool! I'm glad it helped this week i'll try it myself. Can I ask which transistors you replaced and which ones? Maybe it's the manufacturer's fault. I blame the power supply (poorly protected phase without panel)
Transistors are good - I replaced them for certainty The bridge is also functional The electrolytic capacitors have not lost their capacity I suspect some short circuit on the diode, but it's hard for me to determine which one I could look at.
I am in the process of analyzing work-around from the Czech side OK2JN2.cz but I doubt that I would find something. I would like a suggestion. I am posting a photo of the module
