    I need to find out how to wire a 3E369D Dayton to a thermostat.

  • Garednck Dec 30, 2007

    Hello,



    I have removed the T-Stat without making a note of where the wires go. I did this so I could match it up. Now that I am back home I have realized I made a mistake. Can you offer me some help?



    I have a Rudd UBHC-17J11NFD and Model T M 1802 01416.



    The T-Stat I purchased is a Ritetemp 6025

On the Goodman control panel each wire is marked (on the PCB board) Y, R, B, W, Br etc. These should also be letters next to the screws for the wires on the thermostat. match the letters/colors to both sides.

Wiring diagram?


Go to the mfg website and see if one is available to download. Go find a similar unit and take some color pixs if no book can be found. Good idea to draw a diagram and label wires before taking off if you are not familiar with unit.

Inside Fan comes on but when you switch the thermostat to the on position it blows the circut board 3 and 5 amp fuses. All wiring was checked and eveything is wired correctly


Try disconnecting all control wiring at the furnace to the thermostat, then jump "R" terminal to "G" terminal, the fan should come on, then jump "R" to "W" the heater should come on, if the fuse holds after testing the problem is either with the control wiring to the outdoor control wiring or the thermostat and or thermostat wiring.

There is a short in the control wiring that needs to be tracked down. Ohm the wiring to the low voltage controls, ie thermostat wiring and thermostat. Try disconnecting the thermostat wires to rule out the problem in the control wiring to the thermostat or thermostat itself, then install a new transformer without connecting the thermostat wiring, jump the red and green wire at the unit low voltage connections to test blower, and then add yellow for compressor, should be no more than 3 amps on control side wiring with A/C on.
If the problems still exists without the thermostat wiring connected then there is a problem in the wiring in the unit or control board itself.

3 amp control power fuse blowing


You have a shorted control wire problem with either the thermostat, wiring to the thermostat and or the wiring to the outdoor unit if used. Disconnect all the thermostat wiring at the unit and thermostat use a meter to check for a short.

The white wire goes to W2, the green wire goes to G, the red wire goes to R, the orange wire goes to W or O, and the Yellow goes to y. If this is a digital thermostat you will have to go to the set up mode to set the system up for a heat pump or the reversing valve in the outdoor unit will be in the heat mode. If there is a C on the thermostat you will need to put the black wire there on some Trane models.

Wiring instructions for Thermostat Honeywell with Carrier Package


Jumper R to Rc and hook hot wire from transformer to R usually red wire
O = Reversing valve probably white or orange If you get heat when calling for cool or Vice Versa then switch wire from O to the B terminal.
Y = Contactor usually yellow
G = Blower usally green
Jumper Aux to E need to go to unit and use the wire that goes to your Auxiliary or 2nd stage heat
L = Light if you have this terminal on your unit then hook it up.
C = Common from transformer usually black, if you have this terminal on your unit hook this wire up.
Make sure you go to your unit and only hook these wires up if they go to these locations.

I have a singer wall thermostat. I am replacing


You have to know what the wires go to.

(1) wire will come from the transformer and it connects to the r/c and r/h

(1) wire will go to the gas manifold and goes to the g

(1) wire goes to A/C and connects to y/o

(1) wires goes to the fan

My furnace doesn't stop!


Control board is bad or there is a short in the tstat wiring. What you do is remove the wire from the w terminal. Or if you don't have a control board, you will need to trace out which control wire tells the heat to come on. Disconnect this wire and then turn the unit back on. If the unit doesn't come on, then you will know that there is a short in the control wiring. If it does, you have a short within the unit. It will be a matter of tracing it out slowly but surely. Hopefully you will find it rather quickly.

Wiring a thermostat.


The green one is for the evaporator fan motor relay. The white one is for the heat sequencer. The one coming out of the transformer is usually red BUT it will be the power so attach it to the terminal labeled R on the thermostat. If there is a RH and a RC, put a jumper in between them. See if the purple and brown ones go to the fan motor, if so, then just cap them off with wire nuts, and that should have your heat working. Check to make sure the green and white wires go to their designated areas (the heat sequencer looks like a stacked set of thermal overload switches and the relay looks like, well, a relay) and neither ground out before flipping on power or you will pop your transformer.
