What kind of system do you have? The fuse is usually located on the circuit board inside the furnace/air handler. It's probably a spade type and would be either amber or purple. 3 or 5 amps.

    If you have power to but no 24 volts from the Transformer then yes you fried it.

Had a replace batteries flashing when i noticed air wasn't working. replaced batteries on the thermostat and still not working


Turn off breaker. Remove red, green and yellow wires from tstat. Wire nut the 3 together. Turn on breaker. If unit runs and cools you have a bad tstat

I installed a goodman 5 ton heat cool unit and a 5 wire battery operated tstat, the unit is 2 stage will it work with this tstat cant get anything to work even jumping the tstat


See if there is 124 VAC across the common and the red wire. If not then the thermostat transformer inside the unit will have to be replaced or the fuse changed if it has one(not likely).All t/stats are not the same. If your T/stat doesn't have a provision for the 2nd stage or emergency heat then you have the wrong T/stat That will definitely blow the transformer that supplies 24 vac to the control relays

When door switch is energized, blower starts then fuse blows on circuit board within a second or two. I have disconnected all tstat wires to the board. Issue continues.


The fuse should have nothing to do with the blower....so you should be experiencing a direct short within the control circuit. Look for the obvious...like burned or charred wires off of the sensors and other components or melted insulation on a couple wires allowing the wires to short together. Not a lot to go on here, but like I said earlier, start with the obvious.

How are the wires connected from intertherm thermostat to nordyne E1EB-015HA unit


There's probably about 10 different ways to wire them together. If rh & rc where jumped together an tstat then R-RED W-WHITE G-GREEN Yellow (from tstat) to Red to outdoor unit if that's what they had connected outside(should be a red & white outside). If rc & rh were not jumped together @ tstat? The unit has 2 transformers and its a bit different. Rh is 24v from the inside and rc 24v from outside. And also we can use any color we want so who knows what the last guy used. Try this, install the new tformer and at the line voltage wire(L1 or load wire) get a couple of spade connectors(terminal clips) and put one on the tformer and one one the line wire. Then use a 3amp or 5amp blade fuse(auto parts store) and connect your line voltage wire end and tformer wire end to that fuse. But don't let them touch metal or each other. And buy a handful of them fuses(no greater than 5a!!). This protects the tformer as long as its done right. Then reconnect what you remember to be right or just connect 1 wire at a time. Try fan on and cool or heat, 1 wire at a time, and if the fuse opens you know that one is wrong. There is no way you can get the answer you need without knowing what wires are connected to what inside, outside and at tstat. Hope this helps and WORK SAFE!!!

I set the tstat to cool everything ok i set tstat to heat it blows the fuse on pc board


Check for wires rubbing together from the thermostat to the furnace. More than likely there is a short somewhere in the low voltage wiring. Check the wires on the thermostat also to make sure none are touching together.

3 ton carrier split unit heat&cool,mod#38QH036300DL, Heat is good, thermostat will not shut it off. only way to shut the inside unit off is turn off the circuit breaker


Sounds like a bad tstat. The Tstat does control the on and off of the unit.
You can check the Tstat by taking off the white wire to the tstat and turning the heat to the on position and if it still comes on you have a bad wire. If it does not come on then you have a bad tstat.
Another option is to open the furnace and look inside at the control wires and follow them back to ensure that they are not shorted together anywhere inside the unit before checking the tstat wires.
If its the control wires then follow option 1 if not follow option 2.
1.Normally people who run tstat wire pull more wires than necessary to the tstat. Because of this you can use a different one for the heat which is white on the tstat. Remember that if you use another color on this then you need to change it on the inside unit as well. Otherwise it will not work. In other words change it on one end of the line you have to change it on the other to make it work.
To check the tstat wires, use continuity. Take all the wires off the tstat and the inside unit. These are the small control wires, not the main 110 wires. Check each one against each other to see if any of them are shorted together. Be sure to write down the wire colors and the terminals that they belong to on both sides before you take them off otherwise you will have big problems...
If you do not have another wire then pulling a new wire will be the next option.

2. If this does not solve it, then its the TSTAT, Replace it. Hope this helps.

Dryer functions but no heat; only cool air

Just had a honeywell th4000 installed but the heat won't cut off? The temp keeps rising had to cut it off just so I wouldn't burn up? Tried setting the temp down to about 67 but the temp just kept rising


Sounds like they either wired wrong or they got the white wire touching the red wire. Take the cover off the thermostat and see if you can tell if the white wire is touching the red wire. Installers are bad about leaving tag ends on the wires and they end up touching other wires. Good luck

Tstat wiring


Thanks for your Question,
one of two possiblities, first and most likely is that you have blown the Transformer in the Furnace, second would be that you have blown the small car fuse that is on the circuit board in the furnace, if you look really hard you will find it, it looks like an automotive fuse, should be about three amps, if it is the fuse, then its a simple fix, make sure the power is off, replace the fuse, if its the transformer, a little more involved work is needed, but still should be pretty straight forword, and again, please make sure the power is off when replacing, hope that helped ! please be sure to come back and let us know how I did for ya, thanks again,

How to wire 1 plf 1504d heater


I have the solution, finally after looking for 2 days.

First off, I couldn't quite put it all together based on what I was reading. I finally tracked down the Fahrenheat web site (www.fahrenheatpro.com). And called tech support (800) 452-4179.

To wire 2 BB units to 1 tstat.

1. Use #14 wire for 0-12 amps, #12 wire for 12.1 to 16 amps and #10 wire for 16.1 to 24 amps.

2. I have a 12/2 wire going from the tstat to BB#1 and another 12/2 wire going from BB1 to BB2.

3. Onthe left side of the heater, you will have 2 sets of black wires tied together with a nut (on right side it's 2 sets of Black/Red wires). You can use either side of the heater. For the purpose of explaining this, lets use the left side, 2 sets of black wires.

4. Undo one of the sets of black wires (it doesn't matter witch), the other set will be left alone.

5. Take the black wire coming from the tstat and tie it into one of the black wires from the heater and the black wire going to the second BB unit. So you will have those 3 wires tied together with a nut at the 1st BB unit.

6. Take the white wire coming from the tstat and tie it into the other black wire from the heater and the white wire going to the other BB heater. Again, you will have 3 wire tied together here.

7. At the second BB unit, tie the black wire coming from the 1st unit to one of the black wires in one of those 2 sets of black wires. Again, only undo 1 set of wires at the 2nd unit, leave the other one alone. Tie the white wire coming from the 1st unit to the other black wire.

8. Make sure ground wire in grounded at the tstat and at both BB units.

Hope this helps...... If I was less clear than I hoped, call tech support and they will walk you thru it....

Kevin.
