Question about Heating & Cooling

1 Answer

I've posted a question about replacing the fused disconnect with a set of breakers. I'm a bit confused about which wire goes where. The answers I've gotten have been helpful but I still need a bit more assistance. I'd like to send photos of the set up to someone who can interpret what goes where. I've got a Nordyne electric furnace model FEH017HA-04 with, I think a dual power supply.

Hi, I can try and explain this to you without any info? It is fairly easy to do. If you have a box that has a total of 2 fuses side by side then you have a 220 volt service box.If you do have a meter, you can check across the 2 fused wires, switch on, to see if it is 220volts or more.What you need to do is to replace the fuse type box, lets say the box is a 30amp, or 60 amp box, with a box set up with 1- double pole breaker of the same amperage. Take the box to Home Depot and they will show you what box you need.You can do this very easy, step by step. A 2-pole breaker box will have a double breaker inside of it. It will have a silver lug to terminate the neutral wire. The 2 hot wires, take one at a time and one will go into the screw on one side top of the breaker and the other into the other side. This is called the line side, power in.Now, the wires from the furnace will terminate the exact way, one hot to the bottom of breaker and the other Hot to the other side of the breaker, which is the load side, or furnace side. The neutral to the silver lug, and if you have a bare copper wire, it will go to the box if no lug or terminal strip for ground, you can screw it right to the box.It sounds difficult but is very easy. I know you can do this. Be sure you change the fused box with a breaker box, very inexpensive. Just picture the 2 fuses side by side, and the 2 hots will be the 2 that terminate at where the 2 fuses terminated, line side, load side to furnace. You only have maybe 4 wires, 2 insulated hot wires, 1 insulated neutral, and may have a bare ground. That's it for a 220v, 240, v, 208/277volt.Hang in there you can do this. Feel free to send me a link to see this, if they allow it, I am not sure of this. Let me know please and I can have you up and running in no time, Sincerely,

    I am sure you have solved this problem with replacing the fused box with the breaker box. I hope I was of some help to you.I failed to mention or ask if you had a 3-phase system, which would have had 3-hot wires coming in with the same voltage. Anyway, if you could rate this I would be grateful, and will know if this problem has been solved. Thank you for using FixYa and hope you continue using us, as we have some outstanding techs working here to solve these problems for good folks as you.
    Sincerely, and happy holidays, Shastalaker7

I just wired my hot tub into my new house. And GFCI keeps tripping?

Still would go with Miswired.
if this is an auxiliary GFCI Spa Disconnect,
240 VAC, 50 Amp, then...
All of the following needs to be this way:
  • 4 wires from MAIN Circuit panel, into GFCI disconnect box, 2 hots, 1 Neutral, 1 ground
    • 2 hots go onto the disconnects Power Bus Bar for breaker
    • 1 white Nuetral goes to Isolated nuetral bus bar
    • 1 green Ground goes to ground lug directly on the box
  • 1 GFCI in the auxiliary disconnect box
    • The White Pigtail of the GFCI Breaker goes onto the Isolated Nuetral bus bar. There are now two wires there.
  • 4 wires come into box from Spa. (Unless the spa is Specifically a 3 Wire Connection Spa!)
    • 2 Hot/Line wires will go into the L1 & L2 lugs of the breaker respectively.
    • 1 White Nuetral Wire will go into breaker as well at the "Load Nuetral lug, usually marked as 'LN'.
      • It will NOT go on the Isolated Nuetral bus bar.
    • Green Ground wire will be connected to ground lug, 2 wires are now connected there.
  • Connections at spa will be respectively connected: the 2 hots on line 1 and line 2. White wire goes to Nuetralnd green ground will go to a Ground Lug, most likely to metal control box.
If it's not wired in this manner, it is wired WRONG.

99 Carolla pwr windows not working.

You'll have to get someone to trace the circuits to find the short. You can unplug the master switch in the driver's door and use a circuit breaker in place of the fuse or a fresh fuse.
Toyota door switches have a history of problems. If you disconnect the master switch and the new fuse or circuit breaker does not blow, I would try another switch. You may also have a problem with the wiring harness between the door and the post.
If the new fuse or breaker blows, you will need to disconnect the other motors and switches or look for a short in those circuits.

Model T103 breaker tripoff why

You have T103 120V-240V timer with 120Volt clock motor.
Resourceful do-it-yourselfer did not say if this is new installation that is wired wrong, or if existing timer suddenly shows difference.

1) I have tested this timer. Problem with new installation:
Check wiring against diagrams on following link.
This timer can be wired many different ways.
Add a comment if you are confused about electrical schematic, and say what voltage, color of wires, Load(s) you are controlling so expert can give best answer.
If you do not want free help, then resourceful do-it-yourselfer can re-post clear question and offer to pay for answer.

2) Existing installation tripping breaker.
Chances are the tripping breaker has nothing to do with timer, but is caused by bad circuit breaker or short somewhere between breaker and Load.
Open timer and look for loose wires and burned smell and signs of burning. Snap timer mechanism out of box using thumb spring located top inside box and look for burned contacts.
If timer shows nothing burned, then the short is not located at timer. Do more checking and then add a comment or re-post another question.

Add a comment for more free help.
Also take advantage of fixya expert assistance live.
For a price, expert works with you while you work on timer or any do-it-yourself project.
Fixya is always less expensive than a service call.

Hi, I have the Cutler Hammer fusible ac disconnect 30 amp, my question is with the 10-3 wire from the fuse panel to the pullout do you only use the Black White and Ground and lay back the Red? Also, can...

If you use a white wire to carry a 120 Volt line it would have to be taped with either black or red tape both at the breaker box and your fuseable disconnect so the solution is to use the black and the red wire into your curcut breaker, the white and the bare ground both tie into the grounding post at the circut box and at the fuseable cut off, Yes the fuses are neccisary per code.. to eliminate a short or fault from traveling all the way back to the breaker box.. often times found inside the building the fusible pullout is attached to. check your local codes and regulations for more specific details.

To fix a electrical fuse for a 1975 roll

Easier to replace with a resetable breaker. Safer too. They are readily available from local electronics store. If you are trying to keep it original looking disconnect the wiring and install a self resetting type, more expensive than normal breaker, and hide the wiring to it.

Nordyne FEH017HA-04 furnace wiring

This should be 110v so you will have black wires, white wires and ground wires. The grounds wires both go to the ground bar, the whites wires both go to the nuetral bar, or can be wire nutted together, the black incoming (feed) wire goes to the buss bar that the breaker plugs into and the black going to the furnace goes into the breaker lug.

Q - My electric dryer runs but will not heat, what could stop my dryer from heating?
A - 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.

Frigidaire front loader dryer, Gallery series, blowing cold air only

Warning! To avoid personal injury or even death, always disconnect your appliance from its power source--that is, unplug it or break the connection at the circuit breaker or fuse box--before you do any troubleshooting or repair work on your appliance. Also, because some components may have sharp edges, use caution while working on your appliance.
I attempted to locate an answer to resolve the issue for you, but you have not provided me with enough information to access my service database. Please observe the TIP below, and post me back and I will be happy to assist you further.
If your dryer doesn't heat, check these:

Power from the house
Heating element
Thermal fuse
Power from the house Check to see whether there's power getting to the dryer. Is it plugged in? Check for blown fuses or tripped circuit breakers--your dryer uses two fuses or circuit breakers. The dryer could tumble but not heat if only one of the two fuses is blown. If you have circuit breakers, one of the two circuit breakers can trip, even if the two for the dryer are connected.

Heating element Often a dryer heating element burns out, but doesn't trip the circuit breaker or blow a fuse. The heating element is simply a long coil of special wire. You can check it for continuity with an ohm meter. No continuity means the element is bad and you need to replace it--electric heating elements aren't repairable.

Thermal fuse On many dryers, there's a thermal fuse mounted to the exhaust duct inside the back cover panel. The fuse--which is about an inch long--is usually embedded in black resin and mounted in a white plastic housing. If the fuse has blown, you need to replace it. (You can't re-set it.)

Wiring A common problem is for the main wiring connection from the house, at the dryer, to burn and break its connection. Because the dryer can still tumble with partial power, the connection may be only partially defective. You may need to replace both the power cord to the dryer and the terminal block inside the dryer that the wire is attached to.

If my assistance helped resolve this issue, please show your appreciation by rating how effective my advice was in resolving this issue.
Thank you,
Dave E. (Illeagle)
