Hello!!
I’ve got an old heatslave 20/25 running on kerosene. Came up with a lockout today. Tested everything I could. Symptoms, blower not starting. But… The burner runs and the boiler works if I bypass the “back to mainboard” loop for the blower motor live. To be specific, pin 4 pink wire from 832.3 to main board, yellow is the return. Pin 4 pink goes live 240v but yellow doesn’t, yellow attached to brown motor live wire. The “work around” proves that blower, ignition, fuel pump all work fine, but what safety feature am I bypassing. Going to get an engineer in, just curious. Cheers
