Pentair Mastertemp 400 - Service Heater light

[dougingalls]

Hello,

I have a Pentair Mastertemp 400 (almost 6 years old). I have been getting as service heater light (solid red light on the Fenwal Ignition Controller module - Control Fault). The heater will run normally about 50% of the time that we use it. On the occasions that the service heater light triggers, then I open the front panel and pull the 240V (red) 12 position recepticle to restart the heater and it fires up fine. Any thoughts? Is the Fenwal Ignition Controll Module going out?

Thank you in advance,
Doug

Have you flipped over the top cover to see which diagnostic LEDs are lit on the main board?

and of course, now I cannot replicate the problem. Everything is working again. Such is life.
