HeatMaster 400 stack flue sensor replacement

[tpn7399]

Hi folks. the heatmaster 400 threw an e05 error. heater turns on for 15 seconds and then turns off. all research shows that it is a bad sensor.

The question: Is there a difference in longevity in the Pentair 42002-0024S vs the non Pentair stack flue sensors? Pentair brand is upwards of $70+, non Pentair replacements are $22 on Amazon. Is there a difference? Thanks.

Regards,
Peter

You get what you pay for in most cases. Although it might be more expensive, the real deal Pentair part should be the way to go. I have no clue who makes the knock offs or if they are reliable. I guess the worst that could happen is the knock off fails and the heater melts down.
