Overcrank means that it tried to start and couldn't. It will go through 5 crank cycles and then stop with this alarm. Switch to off, hit enter to clear fault and then try to start in manual. Check to make sure you have fuel and pressure is 11 to 14 in WC.

I have a generator that did the same thing. It would start and then stop within a few seconds. The more expensive generators have an oil level safety switch to prevent the engine from burning up. There is usually a wire connecting to the switch on the outside of the engine near the oil fill hole. Remove this wire and try to start the generator. If it runs without a problem then it is the switch. You need to remove the switch and take it apart carefully and clean it. There is a small float inside the assembly. When the oil runs low the float allows the switch to short to ground which kills the spark to the spark plug. Hope that helps.

need to calibrate the main control board. 83089. also is it overspeed or overcrank? if the board does not see the right rpm or is blow a certain threshold it will think it has not started yet and shut down on overcrank.

How old is it???? Does it have a read out that tells you what's wrong?????When is the last time you did a maintaince tune up on it???? Mine is fueled by propane and I changed the oil and plugs and it's been fine since....Sometimes it's the starter/ignition..I would do a complete tuneup first, then clear codes, then try starting it up manually....If that works put it back on auto..Good Luck

If it was installed only five months ago, it should still be under warranty. Call Home Depot and have them send out a repair person.

Are you sure about that model number?

For the over voltage there is an adjustment on the control board.Should be tested with a load something plugged in.The hertz might just come on when under load and adjusted too.If you need more give a model number and whether it is 13kw or 40kw.
