Craftsman 33 gal Air Compressor 6 hp Horizontal k Oil Free Pump - Page 4 Questions & Answers
I have a 33 gallon
I wasn't able to find the amperage, but if you do use an extension, it should be short and thick like an air conditioner extension. Try that.
On start up, the motor ran slow then popped the
It sounds like the compressor is trying to start under load because there is a tightness in the pump itself or there is high pressure air in the line between the pump and tank There is a small valve that releases the pressure out of the main pipe that runs between the compressor and tank once the tank is full and the motor automatically cuts off. You know this valve is working by the sound of a short spurt if air being released when the motor cuts off. Releasing this pressure means that the motor is able to restart easily because there is no load. If the valve is not releasing this air, the compressor is trying to start under full load which the motor is not capable of doing, hence the slow running, overheating and popping of breakers due to a current overload as the motor tries to run up to normal peed. Motor burnout is possible if it keeps recurring.
This small release valve is attached to the Pressure control switch that switches the motor On & Off and usually has a small pipe going to it or is incorporated inside the Pressure Control Switch. If the valve appears to be working then it means that the Non-return valve on the input to the tank is not sealing properly and letting air back into the main pipe causing the compressor to start under load. Check both valves for correct operation and replace as necessary.
If all the air side checks out OK the check for low oil level and / or binding in the air pump main drive shaft.
AIR PRESSURE WILL NOT GO OVER 40 LB . CHANGED THE
Hi, my name is John. Welcome to FixYa. Check the line coming from the pump to the tank for a split or hole, I have found that this is some how over looked. You may have to remove the line to inspect it. Check all hoses for air leaks. Thanks for choosing FixYa...John
The compressor runs,but does not build up pressure
Hi, my name is John. Welcome to FixYa. Check that you don't have a split line from the pump to the tank, also air hoses,exc. any kind of air leak, check and clean breather, if that does not help, then you are not getting any intake. Thanks for choosing FixYa. ... John
My regulator broke and I just replaced it. Now
Hi, my name is John. Welcome to FixYa. Look on the pressure switch and see what the max. is. I have some notes here I will have to locate them and I will post them here if you still having problems, but it sounds like you need to replace the pressure switch. Thanks for choosing FixYa...John
Kicking braker out
