last week our house was cold and I noticed that the system was not
running. I checked the thermostat. It was set on heat, fan 'on' and
the normal/emerg switch was set to normal (always has been). I didn't
find anything obvious, so I hit the breakers and it came on and all was
good. Tonight however, it seemed hot in the house and sure enough, the
thermostat was set on 70 degrees, it was nearly 80 (checked on the
thermostat and 2 other places in the house) and still blowing hot air.
I've done all I know. I played with the light switch on the inside
unit (fan cutout, I guess). THe outside unit keeps running. I've
flipped all the breakers, played with the setting on the thermostat and
even flipped the normal/emerg switch to 'emerg', but the outside unit
keeps running. It keeps running even when the fan stopped engaging. I
finally pulled the big fuse on the outside wall, by the outside unit.
Any thoughts (besides calling the local Trane service rep in the
PS: changed the filter about 2 weeks ago.
Except, I recall one of the regulars ( Nooner ? ) here was asking about
trane just the other day--and since I just recently had some minor issues in
re-commisioning one ( American Standard belonginging to my own brother )
just last weekend ( after his having a prolonged power outage, hp main
breaker was thrown, likely due to not allowing time for the crankcase heater
to bring comp up to temp )
Anyways--I thought I'd scan the docs for the heat pump, fossil fuel kit etc.
for future use...
Several pages of fairly hi-res scans, and so you'll need to have some
bandwidth--but should be able to access them at the following link :
Notably, the TDR as depicted on the taystat fossil kit schematic was in
actuality just a std sequencer--garden variety unit as would be typically
found with heat strips--unknown is whether or not the III series t8611* stat
actually had the capability of any heat anticipater setting.
Oh well--a WR control presented in the actual furnace, ( heritage 80 )
system had flatly refused to energize Y at the outside unit untill I had
finally cycled off then back on power to the furnace proper...seems to be
working fine now...( shrug )

Sure. Just keep pulling the big fuse on the outside wall, by the

fix it yourself (which you obviously cant) then you've pretty much
limited yourself to your own "fix".
Try taking the fuses out and replacing them with copper pipes.
If that doesn't work, then sand the coil with an 80-grit belt sander and
douse it with hydrofluoric acid.
If that doesn't work, crimp off the return line with a pair of vice grips.
If that doesn't work, change the compressor oil to Quaker State 10w40.
If that doesn't work, try a new thermostat.
If that doesn't work, then use a reamer on the flare fittings.
If that doesn't work, then you probably need a union tech.
If that doesn't work, then just sit up in the attic and lick a window for a
Well thanks for the one serious piece of advice, which turned out to be
the case (relay) when I called the service tech the next day.
For the other contributors, please consider finding a real hobby or a
therapist, or in some way try to find out why you think other people
enjoy your childish non-helpful banter. If you're always like this,
well I either feel sorry for your wives, or totally understand why you
don't have one.
