Hi there, how are you doing?
We have a "Bryant Plus 90" which was purchased about 10-13 years ago.
It's been working great until about a year ago we had to "reset" it
and it went back to work. Recently the LED shows a error code (31,
three short blink and then one long blink) which according to the
PRSSURE, DRAFT SAFGUARD, AUX-LIMIT SWITCH(WHEN USED)OR BLOCKED VENT
SWITCH(WHEN USED) DID NOT CLOSE OR REOPENED (DOWNFLOWONLY)
If open longer than five minutes, inducer shuts off for 15 minutes
* proper vent sizing
defective inducer motor
* restricted vent
* low inducer voltage(115VAC)
defective blower motor or capacitor
* defective pressure switch
inadequate combusstion air supply
* disconnected or obstructed pressure tubing
If it opens after trial for ignition period, blower will come on for
90 sec. recycle delay.
Just wondering if anyone knows anything about typically for such as
gas heater, if got this type of error code (33), what type of problem
