While I do not disagree that "lots of people "DIY" things they shouldn't", there is no law that prohibits a home owner (in Ontario) from doing their own gas work. The only requirement is that they have to be the home owner and the work has to be inspected and tagged by a licensed "gas-fitter". Enbridge did an inspection on my own install for a fee of $65.00 back in 2008. Hence the insurance covers the install.

Ironically, as the tagging is with a paper tag then in all probability that tag will be burned up in the event of a fire.

...the only thing they had left to their name was a $300k mortgage and no home to show for it.

because lots of people "DIY" things they shouldn't...an acquaintance of someone i work with installed their own gas heater in their garage as he wanted a warm garage to work in...about a month later, the whole garage and house burnt down...after an inspection, it was due to faulty installation of the gas heater and the insurance company refused coverage...they lost everything, and the house was only about 1 year old...the only thing they had left to their name was a $300k mortgage and no home to show for it.

DJ, installing a "Gas heater" and installing an electronic switch are two different things.

I did notice a little bit of water on one of them but thats probably normal since its hot air coming out of the exhaust and its cold outside.

I have the same York POS furnace, This is known issue, I have been replacing the pressure switch yearly, always in the fall before the frost hits. There is a big thread about these junk pressure switches failing on a DIY HVAC forum, Google will find it, if not I'll look it up for you.

I just replace them, because for less than $20 bucks a pop, I just do it myself and make sure your pipes are clear and your install is correct.

If you're not familiar with the part, why would you comment that he might need a gas fitter.

Got a email back from York asking for some info about the company and furnace, hopefully they can help us out.

only issue now is that the furnace has been working ok the past day or 2 now that the temps are rising again.

Check all your dampers, and filter make sure there's no obstructions in your duct work.

If you want to get nasty about it, report an unsafe installation to TSSA with the installer & company name.

You can also write York and tell them that you are going to write CSA telling them about an unsafe product.

Then see what happens.

Did they ever try replacing the control board (the brains, or there lack of, for the furnace)?

Yes I may have to call York since I have not gotten an email reply from them yet (only been 2 buisness days) I dont think they have a Canadian location as I cant find any Canadian contact info on their website.

Thanks

And if you cycle power to the furnace it begins to work again magically?

EDIT - opps ment to say mine also gets tempermental at times and fails to work, power cycling helps 99.99% of the time.

How do you know its the pressure switch, are you going by the diagnostic code from the system board LED?

I had a similar problem if you're talking about the switch that detects if pumping air through the combustion chamber results in negative pressure. There is an intake and exhaust pipe leading outside. After two visits from Enbridge that didn't solve the problem, I discovered that on the intake pipe frost had built up to the point that it couldn't inhale. The exhaust pipe created a plume of steam on very cold days and the intake pipe sucked it in. There is a plastic rodent screen on the intake; the frost built up on that. Removing the screen cured the problem. So far no mice have made a home in my furnace.

Don't know if this is your issue, but might be worth a look.
