Bryant 340mav furnace
Posted by Frank Garza on September 29, 19100 at 07:03:00:
Hi. I have a BRYANT model 340MAV high efficiency furnace that is 4 years old.
Last year, the furnace would stop running due to a pressure switch fault. I have
verified that the air flow is indeed ok. The problem seems to be the pressure
switch itself - the switch or contact within the unit is intermittent. If I jiggle the
wires and/or contact on the switch, the contacts close and the furnace will start
back up.

Obviously I need to replace the switch. However, i've been unable to find a source
for Bryant parts (consumer, not contractor). Any suggestions ?
Thanks in advance for your help.
