Question about Water Heaters
When i am trying to put my central heating on, the burner light isnt coming on and then the lock out red light comes on. please could you tell me why this is happening
These furnaces have a sequence of operation , 1 thermostats calls for heat,2 purge fan checks flue is open and not clogged ,3 checks to see if hot plate ignitor or spark ignitor is on 4opens gas valve 5 checks for flame and allows valve to stay open 6 checks for temperature rise and brings on fan , if any of the process is not there or interrupted trys 3 times and defaults to lockout , that is the best answer with out knowing what type you have , hope i helped
