Nice video. I now understand why a bad check valve at the tank entry would leak to a leak through the pressure switch when the pump is not running. The same action that opens the electrical contacts also opens the unloader check valve. The reason that the normal rush of air when the pump is shut off is so short is because, with a properly working tank check valve, only the small amount of air in the lines needs to equalize. Thank you for this
My compressor won't turn off! Now I'll be able to see why the pressure switch isn't working properly. Thanks for showing how these things work, great explaination, easy to understand.
Excellent presentation! My pressure switch has just failed - can't actuate the On/Off switch button coz its push rod is stuck in the up-position and can't push the button down with the compressor air reservoir either empty or near full pressure (manually filled from the 240V supply) - no difference to the On/Off switch position! What symptom(s) did the small air dump valve exhibit when yours failed ? I think my dump valve has also failed leaving pressure in this line??? Did you have to purchase a complete switch or did you source a replacement dump valve?? Where did you source your replacement part from? You are obviously an Aussie and I hail from Gippsland, Vic. Cheers
Thanks. Yes, I'm in QLD. Hey, check out the attached video to me fixing my compressor with this issue: th-cam.com/video/Kczx5lMaDzM/w-d-xo.html&ab_channel=JELReviews Hopefully, it might help you solve your issue.... maybe. It has there in the description where I purchased my replacement switch from for the cheapest price.
Tnq for the video, but maybe u can help me. i change my preasure switc to the new one and its wont stop pumping. Where i can find the problem? Theres no air leak from the compresor. But it cant pump more then 4.5Atmospheres. its a 8A compresor. Please help :)
Hmm, sounds like a possible starter capacitor fault, might need replacing, not sure. Here's a helpful forum thread that might help... www.mig-welding.co.uk/forum/threads/compressor-motor-keeps-blowing-fuses.89994/
Wow...a wicked explanation as to how this works. Cheers mr. Saludos from islas Canarias...🌴
Thanks for watching... Glad it helped 👍

Well done video. I have a bad unloader valve. This is exactly what I needed. Thanks so much.
Very nice upload please keep up the good work. Kind regards from uk.
Thanks for watching, much appreciated. :)
REAL GOOD video with explanation
Good clear explanation, thanks
Good To Know. I Just Bought Me A Small 3 Gallon Air Compressor For $5 At A Yard Sale About A Month Ago. I Have never Seen Pliers Like Your Before.
Glad you finally got a Compressor 😁 What a bargain! Yeah, these are plumbers pliers... Very handy in certain applications

Yeah, hope it helps! It'll be either unloader valve, or tank motor air inlet check valve. 👍👍
@@jelreviews I'm sure this info will help me sort it. Cheers
Gracias❤
Perfect, thank you a lot 👍

Compressor starts ok but when pressure drops and tries to restart it blow fuse
