I have a dual pressure switch. Should both show a reading on the terminals? So far I only had a read-out on the one. Thank you in advance.

multimeter display ol, what's meaning? Thank you

@Trontaneous 8 месяцев назад

OL=open line. Meaning the contacts haven't closed(made connection) to allow ignitor to glow and then gas valve fires up.

Also you can read to much resistance which is happening to me without motor running it shows ol, with motor running its showing a lot of resistance I would have to do it again to give exact reading its higher than a lil over zero

@Seabass1206 10 месяцев назад

you got to isolate when checking resistance

@martyturpen4535 10 месяцев назад

@@Seabass1206what makes you think it wasn't isolated? Only thing that was hooked up was vacuum line

@bills6946 Год назад

If the inducer motor is running and the switch doesn’t close, it doesn’t prove the switch is bad. You can have leaking tubing, clogged tubing, a slow motor (defective) or an obstruction in the flue pipe. Further testing is required to determine the problem. The Repair Clinic needs to take down this video

@jimbarron8688 11 месяцев назад

Agreed. Doesn't show them well.

@ras808 10 месяцев назад

They say right at the beginning that the problem may lie with a slow inducer motor

@hemayetahmed5007 10 месяцев назад

agreed

Thanks to this advice I found that a spider had gotten sucked into the vacuum hose and clogged it up preventing the switch from operating. No new parts needed.
