"AGS" problem. Has a new ignitor. Water flows freely
I have a "Service" light and the "AGS" light is also lit. The skimmer/pump baskets and the filter are all clean. The pump flows freely and uniformly. I have replaced the Hot Surface Ignitor, although the ignitor's probe did not come with the kit so it is still the original. This heater was installed in 2002 and has had no repair issues until now.

The probe should be thuroughly cleaned. That may be the problem. They have to be clean in order to maintain a certain temperature. If dirty, temps fall and pilot won't stay lit. Also check your gas valve to make sure spring is not weak and you get a good flow of gas. If you have done these steps and it is still happening, then you may want to consider doing some testing of any relays and power to the system
Also take a look at the AGS (auto-gas shutdown) system
The AGS and service light can come on for these reasons:
No Flame at burners
Low gas pressure
Low Oscillating Pump Pressure
Check these things:
Filter is clean, Pipe line blockage, flame sensor, and ignition problem. (dirty probe)
This system has 6 switch/components
Pressure switch
Hi-Limit Switch
Air Flow Switch
AGS
Temp Sensor
and 2 extra switches
The owners manual has some good diagrams if you need them.
