    Rheem RKMB roof top high limit lication

    Hi, was doing a pm on a Rheem RTU, all 3 Ventura motors were running and I had a error code for high limit(3 flashes). I checked blower section, heat exchanger compartment, Ohm’d out 3 resettable rollout switches( all closed). Any thoughts of where I might find the high limit on a Rheem? Schematic has it coming off a 10 pin plug off board ; two orange wires disappear into bulk head.

    It seems to me I saw this same question in another thread. Please just make one post. Also note that AOP is the wrong place for technical help.
    AOP Rules: Rules For Equipment Owners.

    Free online load calculator:

    There = not here. Their = possessive pronoun. They're = they are
    It's = contraction of it is. Its = the possessive form of it
    Too = also. To = expressing motion. Two = 2
    Then = after that, next. Than = indicates a comparison.
    Questions should end with a question mark "?" Statements end with a period "."
