Nordyne FEH017HA-04 furnace wiring

I've a Nordyne FEH017HA-04 furnace. The fused disconnect melted due to corrosion on the fuses. I'm replacing it with a breaker kit. However, when I took the disconnect off I didn't realize how long it was going to take for me to find a fix for the problem. I don't have all the wires marked and I'm now unable to complete the rewiring. I need someone to talk me through which wire goes where.

    This is, I'm supposing, a dual supply furnace. Besides the two ground wires there are two black, heavy gauge wires and a white and black lighter gauge wire. 220 and 110 volts, correct? I've also got questions about the other wiring on the furnace. This would be the wiring to the sequencers and furnace limiter. I've got pictures of everything and a wiring diagram but the diagram isn't clear, to me, at least. I can send the pictures if they'd be helpful.

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.

You have an electric furnace? Is it 440 volts? Or is this the electric part of a gas or oil furnace?

We are talking about a power supply FOR the furnace, right? NOT a furnace control, right?

Vopltage doesn't make any difference here. You had fuses (at some electrical valye) and you are replacing them with breakers of the same value. You have 1 or 2 or 3 or 4 hot wires, a ground probably and maybe a neutral (white) because you may have something in the unit that is 110 V.

All the hot wires go into the top of the new beaker (how do you turn this circuit off ... at a power panel elsewhere?) and your furnace wires go into the bottom or protected side.

If I missed the boat here, please let me know so I may more properly reply to your problem

Have a 1990 chevy square body with two spots on the fuse block that are melted both are were the fuse goes in to the ecm spot should I try to just put in another fuse block or buy a new wiring harnes


You need to figure out what caused the melting. A short perhaps? Fix the electrical issue, then replace the melted parts. Melting parts should be a warning that too much current was flowing through said part, or there was high resistance (at a mechanical connection) due to corrosion or poor electrical connections. You were lucky a fire didn't start. Your ECM may be fried, sorry to say. Lastly, always use the correct rating fuse.

Nordyne furnace FEH017HA-04 the fan runs full force when the ac is on but half speed when the furnace kicks in


That is probably normal if it is electric heat to slow the air over the heating elements. Even some gas units do this. Check to see if the unit blower motor has wires for multiple speeds.

Nordyne FEH-017HA-04 furnace fan is running full speed on ac but not on furnace


Multiple speed fans are always wired to run on "HI" for A/C and a lower speed for heat. If there are more than 3 wires on the fan motor, its probably a multiple speed.

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...


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,
