First, when installing this pressure switch, the gas tube goes to the front smaller opening under the red dot, the connection with the smaller colored opening. This was different than the old pressure switch on my Frigidaire furnace that was installed back in 2003. My furnace was turning on but not igniting and not turning on the blower motor. The HVAC company I called told me it was the transducer motor, which by an odd coincidence is the most expensive part in the furnace. They replaced that at a cost of $500. It did not fix my problem. I was angry. I now dislike tradesmen. I did some investigating about my furnace's symptoms and determined it was either the pressure switch or the flame sensor. Flame sensor was just cleaned. I purchased this. I installed this two months ago. Furnace has worked perfectly ever since. If you call out a tradesman for a repair, make sure you get it in writing that if their diagnosis is incorrect, you will get your money back. And always replace parts from cheapest to most expensive if you're flying blind, not most expensive to least expensive like a tradesman will do.

Worked fine, however, it turns out the switch was not my issue but a bad seal between the blower motor and the plastic collection chamber where the rubber lines connects to. Because of that bad seal, the line was not seeing enough vacuum to activate the switch. Now I have an extra in case this one ever goes bad. :) Still cheaper than getting someone out here, and luckily it went out at early spring, not middle of winter.

Great replacement. Fixed our furnace. Different layout than the dead factory switch but the gas hose goes to the intake under the big red dot on the front. The other (impeller?) hose goes to the “rear” connection.

When furnace goes into to start-up mode but fails to ignite the two things to check first, if you want to save a service call, first make sure air intake and exhaust are clear (wasp nest, snow/ice) then the second thing is the pressure switch. This is the second one I've replaced in 10 years. Two screws, two push-on terminals, 5 minutes. Now I've decided to keep a spare so I bought two (cheap) Amazon shipping is fast but there are times when you need heat in the next hour. And it's something anyone can do, just shut-off the switch to the furnace first. Also be sure condensate tube (clear tube from furnace to drain) which will cause the same problem. Then if replacing the pressure switch and clearing the air way and drain fail you can bite the bullet and call a service man, but why not save a couple of hundred if you can. The switch I purchased works perfectly. I would recommend every home owner look up the pressure switch for their furnace, and order one on Amazon (very good price) and keep it on hand. Then if your furnace quits when it's sub zero on a holiday weekend you'll be a hero. The wife might even bake you some cookies
