Hi, Is it possible to reverse the operation from Normally Closed to Normally open. That is when power is put on to solenoid it will close or block

Nope. The plunger must pull in to open the valve, to achive what you need would require a major redesign. It might just be possible to "Rube Gldberg" some sort of external set up, remove the solenoid, and mount it beside the valve and use a lever arrangement, but it would be clumsy. Good Luck Terry

If you have the TRANS and FRONT reversed, that's what happens. Check the wiring, I know because I screwed it up :-)

When the knob is removed in the -45 degree position as discribed in the listing, the switch is open circuit. So it would disconnect power to the load when knob is removed.

no unless you use the ohm meter function to check continuity. That could tell you if it's open or not.

Larryyou cut the door off, which I have had to do when the electronic solenoid failed (Sentry has a weak solenoid that will eventually fail). Please read the reviews on this, they are seriously prone to failure and once they fail you cannot open the safe unless to use a saw to cut it openthanksleonard

Other thing is that the solenoid must be completly tight to be used with the computer. You only turn this maybe 180deg maxs to manually open the valve. If you turn more water start leaking. This is normal.

I don't know, I have not test but is a small solenoid on function only on one side; ex.: for the main tank always on with no current and on ( 12V) when is for the auxilliary side. So if you run on the main you don't use current.Regards

Probably already been mentioned but there is a safety switch on the back, directly beneath the ignition button, that needs to be flipped from the right side to the left side before the button can be fully depressed.

Yes but you should consider purchasing a solenoid kit that drains the unit in the event of a power failure.

You may need to change out the rpm sensor. I had a similar problem with an older lift master door opener and it would start to reverse and then go back up. I replaced the rpm sensor and problem was gone.

that was the worst problem on mine. the cord pulled out and is a pain to put back in. I would get an electric start conversion

yes u can but only the starter solenoid. u could probe the control wire on the solenoid directly (this would be the small wire). and apply power,or u could pull the starter relay and probe the load terminal (the wire going to the control terminal on starter solenoid) apply power & starter should spin over.

yes it is a normally open switch. if the switch is similar to the original switch get it. if the switch is not I suggest get a similar switch.

It really was not very hard to do. But what I did wrong was use a pair of channel locks to tighten it. I broke it doing this and had to order another one. If you look at the top of it you will see the valve that pushes in. You will also see a nut on the top, make sure you use a wrench there to hold the solenoid. Good luck.

I use mine to open up automatically in the AM and I manually close it at night. In order to do this I had to get a timer that has a switch that will direct the power through the timer or directly to the motor.

try flipping the switch on the bottom that says throttle it should reverse it

You don't have it wired correctly. The open door is triggering the dome light (power draw) and shutting off the Remote Start unit.
