Hello
I am having trouble with my Pentair Mastertemp 400. I have found some info on this site but none have led me anywhere very positive yet.
heater is a year old and i just moved into the house 3 weeks ago, eater worked fine most every night for 2 weeks. now it attempts to light 3 times and then has a red "service heater" light. the fan comes on but the rushing sound of gas being lit never occurs. I hear a click (3 times) and then it gives up and the red light comes on. After this 3xs cycle the electrical systems igniter control module does 3 red flashes indicating "ignition lockout". I do smell some gas during this process.
I replaced the ignitor so it is brand new. I am getting good flow at 3450 RPM (and other speeds) the cartridge filter indicates 22 psi and the salt cell indicates good flow. The entire system is a year old. (house was built last year)
Parts I have on order and should be here this week are:
Fenwal ignitor control module
Stack flue sensor
High limit switch
heater thermistor (last three came in a bundle)
Any ideas?
