Re: Which of the outside wires is the hot

One of the conductors has a rib impressed into the insulation - this is the "identified" conductor and goes on the nickel colored screw of the replacement plug. the other is the "black" or hot and goes to the brass colored screw.

The cord on my heater is damage can I replace the cord or buy a new one its a PowerHeat Infrared Quartz Heater

Was the cord damaged by an outside factor? Furniture, pet, wear? If so, a new cord is OK. If the cord went bad when using the heater as directed, there may be a failure in the unit -- Do Not Repair! Replace the entire cord from inside the unit with the same (or heavier) sized wire. Don't just splice it!

it could be getting worn out from too much use...go buy a replacement, cut the wire off about a foot from the old plug and install the new plug.

Heater will not shut off it will run 24hrs. even when temp. is above heater setting

seethis procedure and fix it. God bless you
    • 1 Connect the test leads to your DMM. Insert the black lead in the black "common" socket and push the red lead in the red socket labeled "volts, ohms, milliamperes." Set the function switch on your DMM to the "ohms" function.
    • 2 Use a Phillips head screwdriver to remove the space heater's back cover and disconnect the power cord from the switch and heating element
    • 3 Check the power cord for a broken wire. Touch one test probe to first one blade, then the other blade on the plug and then touch the other probe to the other end of the power cord. If the wire is working, there should be an indication of 0.00 to 0.5 ohms between each blade on the plug and a different end of the power cord. If the meter indicates "O.L." on one or both sides of the cord, the wire is defective. Most often, the wire will be broken right at the molded plug or inside the plug. The easiest way to fix this problem is to replace the cord set.
    • 4 Check between the two sides of the power cord for a 0.00 to 0.5 ohms reading indicating a short between the two sides of the line cord. If the heater tripped a circuit breaker, there is a short circuit somewhere in the heater wiring. Shorts in a power cord usually occur inside the molded plug. The short could be inside the cord set, if it has been pinched or cut. Fix by replacing the cord set.
    • 5 Check the thermostatic switch by placing one test probe on each of the switch terminals. Turn the switch slowly through its complete range. The DMM should indicate a continuous 0.00 to 0.5 ohms throughout the switch's full range of movement. An "O.L." indication here indicates a faulty switch, and you need to replace it. The reason that a functional switch could read 0.5 ohms and not 0.00 ohms is that some DMMs read their internal fuse's resistance.
    • 6 Check the heating element for an open circuit or short circuit. A typical radiant heating element will have a resistance of roughly 15 to 30 ohms. A burned out heating element will read "O.L." and need to be replaced. A reading significantly lower than 15 ohms indicates a shorted or partially shorted heating element, and it needs to be replaced.
    • 7 Reconnect the wires that you disconnected earlier and plug the heater in. Check the blower motor voltage if the heating element gets hot but the fan does not work. This is the only test that you will have to make with the heater plugged in, so use caution here.
    • 8 Set the DMM for "AC volts" and touch the test probes to the motor leads. A reading of 115 volts here indicates a defective fan motor, and you need to replace it.

Plug, prongs & a portion of the cord (for about 2 in. from the plug) get very hot when in use. Prongs are actually too hot to the touch. Have replaced the plug once, still the same problem. Any info...

This often times is that the plug (outlet) is not heavy enough to support the heater. Go to your hardware store and buy you a twenty amp replacement outlet, normal outlets are rated ten to fifteen amps. This should take care of your problem, also in doing this check the wire to the outlet and make sure it is not burnt.

I have one of the older models of delonghi but the plug got burned off due to attaching and improper extension cord. Is there a possiblity for the cord to be replaced

I don't know how much trouble it is to access the heater end of the cord but if you can see how to do it, it would be a good time to replace the entire cord & plug. Any of the home improvement stores (if in the US) will have the right materials and you will have the chance to lengthen the cable to eliminate any extension cord. Make it 20' if you choose, the wiring will handle it.
Ask or look for a 3-conductor flexible heavy appliance-type cable with at least a 15 amp rating. This may be marked as 2/12 and will have a third wire for safety ground, generally colored green. The other two will be one black and one white insulated conductor. When properly wired, the white is neutral, the black is 'hot.' The plug will be fairly large and have screw terminals for the three wires. This type of replacement plug will handle any 120 V household appliance. The actual blade contacts that go into the receptacle may have one wide, one narrower, and one round pin for the standard outlet. The wide blade inside terminal for the wire is intended for the white insulated wire, the narrow for the black and the ground (green or green/yellow) insulated wire goes to the round ground pin's screw terminal. These plugs are equipped with a substantial strain relief under which the entire cable diameter is clamped.
Inside the heater's attachment area, there should be currently wires attached that correspond to those in the new cord but if not, they may be marked as in Europe (the brand is Italian) and that may have changed since I left there years ago. If you find the following colors, substitute the paired color for US use:
- Brown = US black = Hot - Blue = US white = Neutral - Green or green/yellow = US green or green/yellow = Ground
If you find anything else, let a professional connect the new line for your own safety.

The plug that goes into the wall heats up to a pretty hot temperature, therefore i have to unplug it. I can only have it plugged in for about an hour. why is the cord heating up??

This is caused by High Resistance. Causes of high resistance could include:
- poor connection....the wall socket may need to be replaced. If you plug it into a couple of other sockets in the house and it continues to overheat, then it is probably NOT the socket.
- broken wires in the cord near the plug end.....replace the plug or the entire cord. NOTE: it is important to make sure the new cord has the proper gauge wire for the amount of amperage on the load.

I hope you find this helpful to you. Good Luck in your endeavor! :-)

Electric Hydronic Baseboard Heater Under Electrical Recepticle

I believe you interpretation of the code is a bit skewed in that the fundamental concern is to not route power cords over a heat source which might cause the insulation on that wire to exceed its rated operating temp and fail. The heaters themselves have shrowds over them so there are no exposed surfaces hot enough to melt wire insulation and when you think about it ..2000 watts disipated over a long baseboard section is not that hot. If I were you, I would go ahead and install them and not worry about the warning.. The warning also removes any liability from the heater manufacturer in the event something happens.. Common sense would dictate that you wouldn't intentionally drape power cords all over the heaters... Just use common sense and not worry about it..

Help! Dog Bit Through Electrical cord on Lakewood 2727. How to replace cord???

another option for you would be to use crimp on terminal connectors(**** connectors) you may purchase these from most hardware stores. Even using these I would still tape around the outside to ensure a good insulating surface.

With no colour coded insulation, knowing which wire is hot

Take your old cord out. If you notice there is one side that is a little bigger than the other. Take a meter and measure the continuity from the larger side to the wire end and thats how you can tell which is which. Do the same on your new cord and that will tell you which one to put where. Like this..... ------>l l<----
