Bryant
23
LockoutPS did not open
A pressure switch is still made when it should be open.
Walk 23 in Diagnose
4 plates — walk the one on the cabinet
First check
1 Unplug the switch with the inducer off
On Bryant 912S this code is the switch made when the inducer is not running. Unplug that switch only. Welded switch, water in hose, inducer still spinning when it should be off.
Expect: Code changes when the harness is open.
If fail: Wrong switch, or the IFC input is shorted.
If pass: Switch/hose path. Go to step 2.
The rest of the walkthrough is Diagnose.
On the plates
- Welded switch, water in hose, inducer still spinning when it should be off.
- One switch — there is no ‘the other PS’ to swap to.
Plates that use 23
Same number, other makers
23 on Bryant is not the same code on these plates.
