My unit has been running great up till now. Just

My unit has been running great up till now. Just started our 3rd season. Ran it about 8 hours yesterday and everything was fine. Today started it up and it was running for about 2 hours, when all of a sudden it shut off. The timer on the remote was not set. I checked the circuit panel and everything checked out okay. What could of caused it to go off suddenly?

Check compressor for high current consumption.Check capacitors. Check fan speed.

If fan speed is low compressor will over heat and trip safety circuit in the compressor. If there are independent fans check both of them.

Pressurewasher runs fine then shuts down and cant pull


Same thing happened to me and I found out that water was getting into the carb filter media. Try taking the carb filter cover off and see if the foam filter is wet. If so, try starting without the filter and see if it works. THis issue used to drive me crazy on my unit, hope this helps.

3/8/09 we bought a 1500WO heater. We are happy with the heater. Last Sunday after we had run it all day, it went off and we could not get it to heat. The temp # was lit up but the dots across the unit...


Actually, I sounds as if it is working properly. What may have happened, since you ran it all day Sunday, is that it overheated and the safety switch shut it off. They aren't intended to run constantly for 8 hours.

My troy bilt snow blower that i bought last season (new) ran great i drained the gas at end of winter and this year is hard to start and runs poorly stalls often and bogs down spits and sputters and also...


I am guessing you did not run a gas stabilizer through the unit. Start the unit and run it while spraying carburetor cleaner in spurts into the carburetor. What has happened is that the small amount of gas has dried or what we call varnished causing internal parts to stick. If that fails, removed carb and disassemble and clean, reinstall.

8 Hours should allow the oil in the system to resettle. Then you can restart or place it in operation. They should be stored on the base.
