tp0d posted : Newer style inducers use a plastic impeller assembly.. Over the years, heat can warp the blades, which make contact with the housing and will slow the rpm of the fan so it does not move enough air to remove the exhaust. More heat == more warp, its a snowball effect.

Good it failed before its really cold, give ya time to fix it rather than an oh-shit moment

all the newer motors are sealed bearings as well, and the motor is probably tired. new part time.

nunya posted : Impeller usually refers to fluid (mixing or pump). Blower is for air. If you go shopping for an impeller for a Trane furnace, your likely to come back empty handed.

Have I diagnosed the situation correctly that the problem is in fact an impeller problem?

Your system detected an air flow fault. You jumped to the conclusion that the sensor was faulty(?) instead of actually doing its intended job and detecting a true air flow problem which appears to be likely the problem.

Replace the the draft inducer assembly (with motor) considering it is "making a racket".

jack b posted : It sounds as if the inducer was the problem all along, the switch just doing it's job locking out the system due to the inducer failure.

Unfortunately the failure code covered multiple components, and you exchanged a normally functioning pressure switch.

In most cases the entire inducer assembly has to be replaced.

tp0d posted : Trane parts do not include a rebuildable inducer fan. Need a new one.

should be 3-5 screws, possibly a little silicone..

good luck

anon posted : The furnace gave a code that it had a pressure switch problem.Upon replacement of the pressure switch the furnace works.Later on that night the furnace never comes back on but the next day it does.(it is set on auto)I openend it back up and it is reading a pressure switch problem again.I disconnected the inducer moter and vacuumed out the flue which is laying horizontal,vacuumed out the condensate line and blew into the line that is connected to the pressure switch.Now when every thing connected it comes on but notice the impeller on the inducer moter is making a racket.Manually tested at the thrmostat and it turns on and off nomally.Five hours later it doesnt come back on.Cover taken back off and the inducer fan moter is hot like it is trying to work.Tapping on the impeller and now it comes back on.Does this mean replacemnt of the impeller or is it fixable?
