It's been awhile since I've had to ask a question, I guess that is a good advertisement for TFP. Follow the pool school and you will have a very clear pool.
I'm having trouble with my Pentair water heater. It is a Mastertemp 250. It started to fire and then quit right away after reading another post I think it was the ignitor/flame sensor causing this problem, when I removed it it broke into two pieces. Waiting for this part.
The other issue was I had a mouse get stuck in the fan and it quit spinning so it caused to AFS(air flow sensor) to cause a fault. With the mouse removed, fan is spinning, and the service heater light comes on immediately. Behind the control board the led light that is on is the AFS.
My question is can I jumper around the AFS switch to see if it is the problem? I know there is plenty of air flow, there is good suction on the inlet side of the fan.
I have the ignitor pulled out now just trying to diagnose if the AFS switch is bad. Does the ignitor have to be plugged in to get it to cycle out of "service heater" mode? No red light on back of panel saying ignitor is bad yet. Im assuming the sequence is to check for air flow first and then try to ignite. I just can't get it to do anything but have the service heater light come on first now.
Thanks for any help.
