I am having problems with my Bryant 383KAV gas furnace
The owners manual can be found here:
My problem is that it won't heat or cool and the blower keeps running non stop, even when the thermostat is set to
OFF.
I think the problem is a result of switching the programmable thermostat from HEAT to COOL or COOL to HEAT too
quickly. I guess I should have set it to off.
The Bryant 383KAV has a status LED code. The LED code is currently reading:
"code 33" - "LIMIT OR FLAME ROLLOUT SWITCH IS OPEN
If limit switch is open longer than 3 minutes code changes to code NO. 13
Check for:
a)Blower motor failure
b)motor start capacitor
c)open flame rollout switch, manual reset
d)inadequate combustion air supply (flame rollout switch only)
e)dirty air filter
f)defective limit switch or connections
g)loose blower wheel"
The units blower has been running for about 5 hours non-stop and the LED status is still "33". It has not changed to
code 13 yet. Here is what the manual says for code 13. "LIMIT OR FLAME ROLLOUT SWITCH LOCKOUT- LIMIT SWITCH WAS
OPEN LONGER THAN 3 MINUTES. AUTO-RESET WILL OCCUR AFTER 3 HOURS. FLAME ROLLOUT SWITCH REQUIRES MANUAL RESET. SEE
#33."
I have already done the manual reset limit switch procedure and restarted the furnace and the problem still exists.
The fan blower is running constantly and the error code is still "33"
What is the next step I should take? How do I test to see if it is a bad capacitor or a bad switch or a bad board?
