Hey Folks,

Thanks for having me here.. I'm Looking for the YORK techs / pros out there that have serviced these beasts for a few years...

I currently have a 20 yr old horizontal unit located in attic providing service as an air mover / gas furnace / ac combo. (ac coil in front)
natural draft unit......
model / serial numbers read as follows:
- May be "1" or "A"
Model No: P-HBD16N07501B SERIAL NO: BLXP119587
073-03150-012 REV A: MFD1090

Recently the DSI ignitor has gone out and has been a real pain in the arse to track down as there are so many obsolete parts for this generation "2" rated unit. I tracked down the dsi at AMerican HVAC parts.com, after much a debachle meddling around with the ignition control module and testing sequence executions. AC works fine, all sequences work fine at a call for heat except for ignition.

Needless to say, I will install the NEW DSI tomorrow and test. If all works , then fine, I have two control modules to choose from and test anyhow at that point.

I have been wondering, after all this trial and error with obsolete parts , a few things...

1. Can the unit be kept in place and the control / safety parts be swapped out for more up to date parts? (ie: hot surface ignition, draft motor, vac lines, pressure switch, digital control board, flame sensors, etc...)

I see these units all doing basically the same job with more efficient electronic "control and safety" parts that I currently do not have. I think upgrading all the parts would be easier than swapping everything out of the attic and probably having to upen and close up some lathing......

Much appreciated guys!

You would just have an old furnace with new controls and safeties.

Newer control board would just have a longer blower delay.
Would still have to use the same temp rated safeties. Along with the same pressure rated pressure switch. Those parts are made for and rated for the heat exchanger of that furnace.
So using newer ones, with different ratings would be a hazzard.

current unit has no flame sensors.
current unit has no ventilation blower.
ie: 20 yr old York and model number.

so new safeties would be an upgrade, no?

The furnace is UL, Underwriters Laboratory Certified and AGA, American Gas Association certified for the original parts. Changing them out would de-certify the whole unit and be against the codes.

Nope.

All safeties must be rated to work with that furnace. As that furnace was designed.

Anything done to it. To alter it from factory spec. Is a none factory approved reconstruction.

Which means it loses all approvals from all safety organizations. And your insurance company doesn't have to pay out if anything goes wrong.
