Why is the solenoid on my fan not working?
The solenoid is normally powered up to pass air to the clutch to keep it from engaging. This problem is occurring when the solenoid is powered down. It is a block and bleed function where it blocks the supply pressure and then bleeds the output going to the clutch to cause it to engage.
Why is the solenoid on my truck not working?
If you then shut the truck off, which kills power to the solenoid, you should immediately hear the solenoid vent the air that is in the line going to the clutch. My solenoid would not disengage until some of the air pressure bled off of the supply in the wet tank.
What should the pressure be on a solenoid fan?
It should release it immediately when the solenoid is powered down. Pretty much must be a defective unit since it says it is rated for 140 psi. No way the wet air is that high of a pressure. Air keeps the fan off no air th fan should come on. Reverse from the m939 trucks.
What should I do about my fan clutch solenoid?
OOO Kaay_ Dismantled fan clutch solenoid for the third time. This time I put a tiny bit of 30 weight motor oil on the rubber pads that seat on the cones at each end of the solenoid. Magically, the solenoid is now operating as advertised. I think mine is having a similar problem. I took the solenoid apart, and there isn’t much to repair with it.
Can a bad solenoid be a sign of a bad starter?
Intermittent operation can be a sign of a failing starter solenoid. Other issues that present like a bad solenoid. Problems that might cause your car to act like it has a bad starter solenoid can include: Bad battery – If the battery voltage is low it will be unable to provide enough power to start your engine.
When does a solenoid need to be replaced?
Starter – Some solenoids are mounted to the starter, but some are located directly inside the starter housing. When this is the case, it may be necessary to replace the entire starter when the solenoid goes bad. Sometimes the starter itself is the problem. Electrical issues can be annoying and inconvenient.
Why is my Ceiling Fan not working properly?
A ceiling fan can stop working properly for a variety of reasons. We show you how to deal with a fan that doesn’t work at all because it isn’t receiving electrical power. Then we move on to other types of fan problems, such as wobbling, humming, and failure to turn properly.
How does a relay and solenoid work together?
Both a relay and a solenoid are devices that receive a low-power signal as a trigger to close (or sometimes open) a much larger circuit with more power. In the case of a starter, the ignition switch signals the relay/solenoid (possibly by way of a computer) and the relay/solenoid switches on the starter circuit to engage the starter.
