DIAGNOSTIC CODES FOR DEFROST CONTROL LEDS
Note: Because the Pressure Switches are monitored only when "Y1" (Input) is active, the code
for pressure switch open will not be seen when "Y1" is off. Instead, the "Normal Operation" or
"Anti Short Cycle" code will be seen.
Also, when a pressure switch opens and caused a short cycle lockout, the pressure switch-open
code will be seen until it closes, then the short cycle lockout code will flash unless it has already
expired.
