Speedaire dayton 4b227 blowing fuses
Greetings Bill, All,
When the tank is empty turn it on no problems fires up and runs great let the tank get too full and it will trip the breaker, anything over 80lb pressure in the tank. Try to start with a pressure in the tank over 40lb and it trips the breaker. I pulled the unloader valve and it's working fine, so went for the tank check valve and although very rusty outer case appears to be working fine. So nothing seized the breaker on the motor doesn't pop only my main breaker. I have tired a stand alone 15a outlet with the same results. Although it did get all the way to a full tank on the stand alone outlet. Am I dealing strictly with a power delivery problem or something else. Any help or suggestions would be greatly appreciated
Good on you for doing the checks you did, and for telling us all what steps you've taken so far.
Unless you have a mechanical issue overloading your motor, based on what you are saying, and the trend to flowing the breaker when the back pressure in the tank rises, I would suggest you next check out the capacitor. If it isn't performing, as your tank pressure grows, so too does the load, and the compressor may be relying on the added power supply from the capacitor that isn't there now, hence it pulls too much current and pops the breaker.d
Good luck, and keep us all posted if you would.
Compressor won't start when it's hot
I have a Speedaire compressor model # 4B227C that will run fine when it's cold, but once the pump gets hot it trips the breaker. I had the motor checked, and no problems with it. Now I've taken apart the pump and no cracked pistons, no worn rings. Not sure where to go next.
Dan, in the absence of an motor or start/run capacitor failing issue, and if the mechanical side of the air compressor is working normally, then that only leaves your power supply.
An electric motor that is underpowered electrically will both run hot and fail sooner.
Make sure your power supply is not compromised by other devices pulling power from the same circuit at the same time your air compressor is starting or running, and that you are NOT using any extension cord except a heavy duty (12 gauge?) model.
