L1 oP Code—Open High Temperature Limit Switch
The L1 oP indicates the high temperature limit switch is open or disconnected. The switch
is located on the cooling system canister. It is designed to open when the cooling system
boiler temperature exceeds 378 degrees Fahrenheit (192.2 degrees Celsius).
On units with non-resettable switch, replace the switch with a resettable switch. On units
with resettable switches, reset the switch. In both cases troubleshoot for the L1 oP fault
cause.
