Engine · Shutdown
Shutdown. TP-7092 defines Over Crank as three unsuccessful starting attempts. The check column says to check the fuel supply, spark plug, and battery, and to check for loose connections, then contact a dealer if it remains. OnCue Plus uses the same fault name Over Crank (TP-6905 cross-reference for the RDC2 'Over Crank Shutdwn' event).
Seen on: 14RCA, 14RCAL, 20RCA, 20RCAL, 26RCA, and 26RCAL sets with the RDC2 controller (TP-7092).
Likely causes
- Fuel supply problem.
- Spark plug fault.
- Weak battery or loose connections so the three start attempts fail.
Checks an owner can do
- Confirm the fuel valve is open and, on LP, that the tank is not empty.
- With the set off, look for a loose battery cable.
- Do not keep commanding starts after the third attempt has already shut it down.
When to call a pro
Spark-plug service and anything beyond a visibly loose cable belong with a Kohler dealer. TP-7092's check line ends at the dealer if the simple items are not the cause.
