Hi all,
Okay, let's start by saying no electrical knowledge Hayward 250fdn heater AO Error. Just clicking when turning on, nothing else. Then just sits for a bit then goes to AO Error.
Following attached picture flow chart:
Is blower damaged? What does damaged mean, looks fine to me, nothing out of the ordinary, so NO.
Blower Vacuum switch wires 'look' fine to me, nothing that sticks out, so NO.
Vacuum tube- Don't see anything wrong with but did try replacing it just in case, same result, so I assume it's fine, so NO.
Voltage plug - I assume it should be 120?, if so that is correct.
Blower Ohms - Tested the Ohms on the blower (actually have a second used one as well) got the correct Ohms for each, and tried both, same result, so YES
Checked the voltage following their pictures got around 110, so YES
Says to replace the vacuum switch- that was actually one of the first things I tried.
Vacuum switch attached pic - I don't have that metal plate, what is its purpose?
On another note, my blower connects to the ICB board with a connector, see attached pic, not sure why, but it doesn't fit without it.
Any ideas?
Thank you!
