Ive got a customer with an Amana GUD115X50A 90% upflow gas furnace.
The plastic inducer wheel blew its top. The Johnstone Goodman/Amana
dealer had the inducer. What they didnt have is the Tridelta pressure
switch that was rusted to "smithereens" from the evap coil leaking on
it for 13 years. They said it is "discontinued" (but they arent always
Anyways, its a
3 wire (C, NO, NC)
I had no luck searching so wondering if anyone else has a local
I actually got the Johnstone one and its going back. You have to guess
at what to set it at. No guide on what each turn of the screw
represents. Id have to get something that draws a -.80 vacuum so I
could set it correctly. I dont need crap like that. I get enough
service calls without futzing with a pressure switch. :-)
The americanhvacparts place doesnt have the right one either. I
wouldnt purchase from them anyways. They are thieves with the prices
Thanks anyways. I'll keep searching
Mars makes a universal replacement that comes field configurable for just
about any set up ,
ive used several of these in a pinch , seems it would cover your need
my local supplier has these in stock , let me know if you come up blank
kit comes with hose , allen key for adjusting set points on the switch
maybe your local supplier may have one ,

Antunes air and gas switches are used all the time on industrial
burners and are a good little switch. Safe-money on the little version
But any switch that will let you field-calibrate should be a winner.
I'd check/set the calibration with a small U-tube manometer. ( even
YOU can admit you suck just a little.... at least .8" w.c. worth
of little? :o) ) and come up with a better calibration then
half the switches dropping off the assembly line.
It turns out Johnstone WAS stupid.
The switch (10207904) is a good number after calling the Goodman Tech
support number. I called back Johnstone and they said it is a good
number but comes up as "obsolete/no replacement". Goodman told me to
tell Johnstone to call Goodman factory parts center and order it. I
did and they did.
Every once in a while you just have to beat somebody in the head.
