Hi all, I've read through the service manual and this and I'm stuck. I seem to have the error where I need to replace the fuse (see picture below). I replaced the fuse....the pilot lights, then the burner goes on for like 2-3 seconds and then it shuts down. Any idea on what could be causing it. Everything I've found is that it is a fuse issue but I replaced the fuse and it still doesn't work. I'm going to try to vaccum out the air exchange top portion this evening......Any other advice would be appreciated.

Is the part that you replaced the "tfuse" ( thermal cutoff-fusible link ) that is listed as pentair part # 075173? The exploded heater view and parts list does not give the location for this part. A photo of the part you replaced and its location in the heater would be helpful. If it is indeed the fusible link, this part melts at a certain predetermined temperature and opens the circuit when a rollout/overtemperature situation occurs. Will be able to help further after photo of the part. Also helpful would be photos of heater with the front cover(s) off.

Sounds like the flame sensor is not proving. if you're comfortable with working on the heater, go ahead and clean the burner tubes/rails, and the gas orifices as well.

Check all of the ground connections for corrosion. With some corrosion or a bit of moisture or a change in environment can make the differnce if the small current the flame sensor puts out is seen.
