Hayward FDXLBVS1930 Blower Vacuum Switch Replacement for Hayward Universal H-Series Low Nox Pool Heater

one for one replacement of old unit, no issues, OEM product and fast delivery. 2 times the price at local pool shop. Great buy. Use this to fix the AO error on Hayward heaters, another option is to blow really hard into the end of the vacuum tube until you can buy this item.

It was an easy fix

After repairman kept blowing me off decided to try and fix it myself. First had a LO error which turned out to be related to the filter being dirty. Once that was solved the heater had an AO error. Ordered this part, unscrewed the old switch, screwed and plugged in the new one, and voila! Fixed in 2 minutes for $38. Can't beat that. Arrived earlier than estimated too.
