Question about Heating & Cooling

Open Question

Taskmaster heater (used) fan runs, thermostat seems to work but barely gets warm. need to see gd schematic for wiring for 240 volts. may be set up for 3 phase.

Obtained used unit. I wonder if it is wired for 3 phase svc. I installed it, hooking it up to 240 V svc.. It runs, but doesn't get hot. It gets warm, but not hot. Possibly heating elements not wired for 240V but I'm thinking it may be set up for 3 phase from it's former location.

SOURCE: Properly installed electric baseboard heater won't work.

I am an electrician. You must measure the voltage across the black and red wires. Measuring each wire to the neutral will not cut it. If both your red and black wire are on the same phase the heater will not work.

To double check your wiring, measure the voltage across the two screws feeding your subpanel, they should be 240v or 208v depending on your power company. Then do the same at the breaker feeding your thermostat. Again it should read 240v.

If you have no potential across the screws it is possible that you installed an incorrect breaker. Not all breakers with two screws on them are 240v breakers. There is what is called a twin or split breaker that has two screws that are on the same phase. These are for wiring two 110v circuits, when you run out of spaces in the panel.

Double check everything. This is a relatively easy circuit to wire, even for homeowners. If the heater does not work them something is wrong so do not leave the circuit energized.

To the best of my knowledge, Noma does not make a high voltage stat (M# would be more helpful). You most likely have a heating only stat that operates on 24VAC. Also, at that wattage, the wires on your thermostat would need to be a minimum of 12ga.

SOURCE: Lakewood heater 7101 schematic

The power cord goes the switch terminal 1 and 3.
Terminal 2 must be the opposite of terminal 1, such that when switched on, 1 & 2 connects. Terminal 4 must be the opposite of terminal 3, such that 3 & 4 connects.
Under this setup, you may connect red to terminal 2
and black to terminal 4.
Be sure of the 1 & 2 pair, as well as the 3 & 4 pair.
then, connect the red and black wires.
Hope this will help you.

How to wire a GE timer switch, model 56922, to my 220v hot water heater, using 2-#10 awg with ground?

You should have received a booklet or manual for the timer unless you got it third party, used, etc.

Anyway, here's a link to the PDF manual for this timer:

From what you described, it sounds like you want to wire the timer using a 240 volt, single phase wiring system.

First, download and print out the manual.

Make sure all power is off. Pay VERY close attention to the switch settings in the timer as to how to set them to run the timer motor on 240 volts. If you want to use 240 volts, then set the switches to the settings shown in the CENTER drawing or the one that's labeled 208~240VAC for the timer motor.

After you verify that, see the schematic in the manual that is located in the far bottom right-hand corner of the page and is labeled 208/240/277V Timer, 208/240/277V Load, Double Break wired as single throw.

The labels L1 and L2 mean the power coming into the timer. L1 and L2 should be one leg each of the power coming from a 240 volt circuit breaker in your power panel rated for the duty. The heater should be the only thing on the circuit. The little box on the right labeled Load means your hot water heater.

The ground wire (green) should be connected to the ground lug inside the heater connection box or secured to the metal part of the box. Attach and secure the other end to the timer case or mounting box which should also be grounded.

Set the timer trip switches where you want them.

Double-check all connections before applying power. Check the timer later to be sure it's running and keeping time.

If you are not comfortable performing this type of work, it would be dvisable to hire a competent electrician to do the work.

My kenmore electric dryer is not heating I checked the heating coil and it seems ok could it be one of the thermostats?

Kenmore style dryer - no heat problems:
Electric dryers - See the "how to take apart" section first if needed. Always check the power supply first...if one house fuse blows or 1/2 of the breaker trips, it is possible for the dryer to run with no heat. If you have a volt meter, you should read 240 volts between the red and black wires, 120 volts between the white and black and 120 volts between white and red, check for this at the main power connection. If you have 240 volts to the dryer, remove rear access panel, turn dryer on and test for 240 volts to the *heating element wire connections (#4). If you have 240 volts there and no heat = bad element, the element must be broken physically to be bad. If you have no power at the heating element, remove power, remove wires to the heating element and isolate them so that they can't touch anything. Reinstall power and check each wire for power from the wire to the dryer cabinet, one wire will probably show 120 volts and the other will show zero. Make note of the color or # of the wire that has no power, remove power to the dryer and check the wiring diagram that comes with the dryer to find out where that color or # wire goes to. EG: - wires might be yellow and red, if the yellow wire (example only) was the one that had no power, look at the wiring diagram to find out where that goes to and check only those parts, no need to check the other colored wire parts as they are working. Things to check are, *thermostats, timer contacts, selector switch, motor switch heat contacts ( 1&2 on the motor switch ) and *thermal fuse. If the wires to the heating element are the same color, just remove power after test and slowly follow that wire that has no power with your hand to see what parts it goes to. If live volt testing scares you, try the ohm checkinstead.
*#1-Thermal fuse that controls heat. If the dryer overheats, this fuse will blow. One shot fuse. Does not reset.
#2-Canister for the heater element.
#3-Hi limit thermostat. This thermostat is a safety thermostat in case the dryer severely overheats. When this safety thermostat is defective, it should raise a red flag for air flow problems.
#4-This is the terminals of the heater element that is inside the canister.
#5-Thermal fuse that controls motor run.
#6-Control thermostat. This is the thermostat that controls the cycling of the heater in high heat mode.
#7-Heater for low heat. When you select low heat, 110V is sent to this heater that the control thermostat sits in. The heater helps cycle the control thermostat faster, therefore you get less heat than the high heat mode.Things that could stop a electric dryer from heating:
- house fuse or breaker ( needs two of them ), heating element, burnt wire, thermostat(s), thermal fuse ( not all models ), motor heat switch, timer, selector switch, burnt power cord/plug.
A ohm meter test for these parts is here.

How do I wire a federal pioneer wall heater 240v with 2 wires there appears to be only 2 load wires to attach to and a bare ground where does a neutral conect to? Thanks Ross

If you are certain that the heater has only two wires and that it is a 240 volt unit, here's what you do:
Bring in a 240 volt line.  There are three wires.  The red and black are the opposite phases and are each 120 volts above ground/neutral.  Connect them to the load wires.  If there is a neutral, connect that to the white wire, even if it is bare wire.  Bare wire and white are the same for all practical purposes.  If the unit has a fan, it will run on the neutral/white and one of the phases. Wire sizing is important.  Make sure you have a properly sized wire for the job Up to 20 Amps, use #12 wire.  If over 20 Amps rated, use #10.  Fuse appropriately.  
Make sure the power is off when doing this work!  240 will KILL YOU.

Install and hot wire heater

You can be assured that the element is 240 volt. The fan motor is also rated at 240 volt. the wires you have black - black are the connections you make to the line. Use a 12/2 with ground. Use a double pole 20 breaker in your panelbox. The green wire is the equipment ground - connect this to the bare wire from the 12/2. On the 12/2 cable - there will be two colors, one black and one white. Wrap a couple of turns of black tape on the white wire both at the heater location and on the white in the panelbox. connect the 12/2 to your 2 pole breaker, the black wire and the taped white to the breaker.
