Probably the MOSFET that drives the glow driver circuit shorted out. Can test with an ohm meter across drain and source. If you measure close to 0 ohms with the power removed that’s your problem.

Take a pic of the back of it.

mine did this
I am a HAM...means.... I am dangerous with a multi-meter
Too many el cheapo surface mount components

VDC output should be 1.2...measured as 11.7 (Batt Voltage....) some component was shorted ..no clue what one

I just replaced it with the slightly more expensive Hobbico version...they are the exact same part so 3 bucks more no diff on warranty....
