Why won't my Unigas PBY93 Burner start?
- RRobert MendezAug 13, 2025
The Unigas Burner might not start due to several reasons. It could be caused by an open main switch, a line fuse intervention, a max pressure switch fault, a fan thermal cutout intervention, or auxiliary relais fuses intervention. Other potential causes include a control box fault, a servocontrol fault, a smokey flame, an ignition transformer fault, a dirty or wrongly positioned ignition electrode, a dirty nozzle, a defective fuel solenoid valve, a dirty or defective photoresistor, a defective HI-LO flame thermostat, a wrong position of servocontrol cams, fuel pressure being too low, or dirty fuel filters.
