Hi all,
The burner keeps locking out on my boiler with increasing frequency to the point it can be every few minutes.
So I thought it was locking out when working but it's seems it gets up to temperature shuts off and this can happen the first time or any number of times.
Quiet buzzing
Louder buzzing
Click constant red light lockout
Reset it goes through the procedure I hear the motor spin then the big whoosh and back to normal, until the next time it starts up again sometimes it whooshes straight away no buzzing, sometimes it buzzes then starts, most of the time now it buzzes then locks out no spinning up of motor.
Cad cell out cleaned tested resistance seems within specs but have ordered new one anyway as the shroud is cracked near the sensor.
Tested resistance on solenoid and got about 30ohms I think across different combinations of the leads.
Could it be the capacitor? I haven't got the means to test that but heard it can cause similar faults. I wish I understood the noises and what they translated to, I think the loud buzzing sounds like HT perhaps the electrodes getting energised but the boiler then not firing? I don't know any help greatly appreciated.
Thanks
Steve
