Do you have the manual? You have to program the wireless remote. Not sure of the exact procedure on this model, but the manual will explain it. If no manual let me know, Countrycurt0

Can't hook up power cord to main motor on Hoover model F5915100


You have a black and white and green wire. Green is ground white is neutral, black is hot . Should say on the motor either L1 = black wire. L2 = white wire , G = Green wire or it say H = black wire, N = white wire , G or the symbol for ground = green wire

How to connect the power to the dryer


most likely 240volts as most 120 volt dryers are already wired,depending on if its a 3 or 4 wire system depending on local electrical codes,but if its a 3 wire cord,take the RED to terminal L1 and Black to L2 terminal on the dryer terminal board HINT:(the RED and Black can go on either L1 or L2 they are interchangable) ,then the White wire to the N neutral terminal on the dryer terminal board usuall between the L1 and L2 terminal,if theres a Green Wire on the cord this is safety ground and can be attached to any metallic part on the dryer,if its a gray flat cord the 2 outside wires are L1 and L2 the center is Neutral,
so its:
RED=L1 or L2
BLACK=L1 or L2
WHITE=N or Neutral
GREEN=Safety Ground the metal dryer frame

I need to hookup up a Grasslin GM40 timer controlling one load and a 120vac application. Just wondering if someone could verify the hookup terminals as I cannot read the schematic as it is mostly gone. ...


Open following links to identify timer and download manual:
http://waterheatertimer.org/Intermatic-timers-and-manuals.html#GM

GM40 can be used for 120V or 240V 277V applications for single-phase and some 3-phase applications.
For 120Volt, set all 4 dip switches to ON position BEFORE applying power.
ON position is pushed to left.

120Volt cable from breaker box has black hot and white neutral wire.
Black hot typically connects to terminal L1
White neutral connects to terminal L2/N
This action will power the time clock and relays.

Other terminals on GM40 are the relay terminals, and these terminals are dry.
Dry means they receive no power when wires are connected to L1 and L2/N.

There are two independent relays and each relay has 3 terminals: NC NO and COM.
If you are controlling one 120volt Load, then use one relay.
Run a jumper wire from terminal L1 to COM terminal.
So COM terminal is connected to Hot.

Cable going to 120V Load has black and white wire.
Connect black Load wire to terminal NO (normally open).
Connect white Load wire to L2/N.

Need to change to a 4 plug


BLACK TO L1 / RED TO L2 these are your 2 power phase wires and you actually can hook them to either power lug on the terminal strip, then the WHITE wire goes to the NEUTRAL terminal sometimes marked just N usually in between the L1 and L2 terminals, then the GREEN wire goes anywhere on the unit that that connects it to the units case which is the SAFETY GROUND

Hi, depending on your local electrical code:and I see that the unit is 240 Volts A.C., then RED=Power/Black=POWER(L1 & L2)/WHITE="N"Neutral/and GREEN=SAFETY GROUND,on the new unit, then use from the wall power BLACK = L1 and White= L2. then on the unit RED=L1 and BLACK=L2(either way you hook these 2 up there isn't a polarity issue on these 2 wires) on the units hook-up/then use the BARE supply wire as neutral and tie BOTH WHITE and GREEN from the unit together to this BARE wire..

Need help wiring new pressure switch for craftsman air compressor


Assuming that you are wiring for 115v. Lets start with the ground. The cord that attaches to the wall outlet will have three wires, green, black , and white. Insert the cord thru one of the openings of the pressure switch and attach the green wire to the ground screw. Next look very closely at the contacts and notice that they are arrainged in pairs. There is a small brass bar with two contacts that completes the circuit for each line. Start with L1 and attach white wire from cord, then attach white wire from motor to the screw terminal that small brass bar bridges to (should be T1). Next attach black wire from cord to L2 and black wire from motor to remining screw. Remember that the small brass bar with two contacts is the bridge and simply connects white to white and black to black. Enjoy
