SOURCE: Heater won't shut off.

you say you hear a click. this indicates the relay is opening and closing, BUT the contacts may have welded itself shut. try replacing the relay - contactor.

SOURCE: furnace problems

On - OK
1 Blink - Ignition failure. Check Gas flow, gas pressure, gas valve, flame sensor.
2 Blinks - Closed pressure switch. Check pressure switch (stuck in closed position).
3 Blinks - Pressure switch - failre to close. Check venter, pressure switch, vent blockage.
4 Blinks - Open limit switch. Main limit or aux limit are open. (My comment - Means overheating in chamber. Often result of blocked intake air. Bad filter. In my case, plastic wrap had been sucked into the intake. )
6 Blinks - False flame sensed. Check sticking gas valve.
Rapid continuous blinking - Incorrect twinning, incorrect primary polarity. Reverse transformer secondary leads, reverse primary wires.

Closed pressure switch can be from dirty combustion vents, bad chamber pressure - like missing screws, maladjusted gas pressure, failing pressure switch, loose hoses, moisture in the hoses or fan blades The switch need to be closed to ge the unit to work

Ok, you either have a inducer fan issue or a pressure switch issue or a plugged vent pipe. The inducer turns on to establish a draft for the exhaust. If it is not working you will get this error code. If the pressure switch does not sense pressure caused by the inducer, it will give this code. If either the intake pipe or exhaust pipe is blocked (even y just a little) it will give you the same error code. If the condensate hose or receptical is plugged, again it will give you this error code. Good Luck!

I have a nordyne furnace model # e3eb-017h. Furnace doesn't kick on at all. No relay click or anything but it's getting power. Did the thermostat trick with touching wires together to kick on the furnace...


Check the pilot light sensor. Have seen this issue before. Sometimes after lighting need to hold it in longer. If it doesn't detect the lit pilot wise it will sit in safety shut down mode

My intertherm e3eb-015h electric furnace will not do a thing even temp.on thermostatdont show up breakers are on still nothing


Check to see if the fuse is blown. If it apprears to be blown, replace it. It is inexpeisive and simple. If you locate the fuse, you will be abel to determin if it is blowin becuase you will be erruption or a burnt mark in the fuse wires.

How do u wire athermostat to the furnance and ac unit on model e3eb-015h nordyne


You need to get low voltage wire known as 5 wire. run wires thru wall to stat and furnace Red wire goes to R terminal white to W terminal Green to G terminal Yellow to Y terminal on both the stat and furnace circuit board. Now you need a wire called 2 wire low voltage wire run that from furnace circuit board to outside A/C. At furnace hook red wire to Y terminal and white to C terminal doesnt matter which ones you hook up at outside unit. Do it just like i told you this will work properly.
If this helps please rate me.

Anyone have a wireing diagram for a nordyne E1EH-015HA


Intertherm does not offer a wiring diagram for the E1 series anymore. So I have included a link to the E2 series. They are very similar and you may find this service manual helpful for whatever problem you may be having.
