I have just today received & replaced the Fan Unit on my Baxi Solo 3 PFL 60 Boiler after the original one started to make a terrible racket & final stopped Running on Saturday (right before the coldest day of the year !!) .
The Boiler fired up first time, new fan ran sweetly but now the boiler runs for a 10 seconds max & then the Pilot & main Burner light trip out & the Boiler fires up again repeating the cycle, sometimes tripping out after just a few seconds. Didnot do this before Fan failure. Rads & HW are both working though (house back to respectable 20 deg from 12 Deg this morning)
The Boiler light & fan light remain on & the fan remains running during the trip out. I checked the voltage to the fan & this is an uninterrupted 240V.
Could this be an APS issue ? I will check the continuity across the White/black connections with the Power off & system cooled down as suggested by other forums. I did trim the Flexible pipes as these seemed hard & brittle at the ends, but wondered if these could have been damaged elsewhere & if this would give the symptoms I am experiencing ? The APS was replaced 12 months ago.
The Boiler seems to run longer (magnitude of seconds) with the combustion box door loosened / removed. Could this simply be a blocked injector due to dislodging some dust when removing the fan unit or something else i.e a PCB problem ?
