The transformer (b) is only supplied with voltage with active gas request. The
glow electrode can be checked visually through the sight glass on the gas
burner.
Check output voltage on the transformer.
The voltage is 24 V.
Check the current consumption of the glow electrode. This must
be at least 1.4 A.
Check fuse F1 on the transformer.
The fuse has blown.
Replace fuse. Repeat test and replace glow electrode if
necessary.
Check supply voltage at the transformer.
No voltage present = Check neutral conductor. Replace
transformer.
Voltage present = Replace ignition electronics.
