I switched on my Pentair Mastertemp 300 natural gas pool heater today (first time this season) and it did not fire up.
The blower is blowing, and everything seems fine, except it won't ignite.
The "service heater" light is on.
I took the panels off and took a smaller metal panel off which revealed a diagnostic LED.
The light was making a single blink......meaning airflow fault.
Upon inspection, it's obvious a mouse (mice) had been building a nest in the blower.
Also, the exhaust doesn't seem as powerful as it used to...not sure though.
All the electrical wires appear to be intact, couldn't find any chewed wires.
And there are no fault codes on the control panel.
Anyone have any ideas?
Is it time to call a technician?
