How to do the internal wiring of my symphony sumo. due to rat problem the internal wires of my symphony sumo cooler has been destructed . so please give a pictorial representation of the wire connection.

If you have enough loose end on the wire you can make a splice and solder the point. Insulated it well with electrical tape. The alternate is to replace the thermistor which and more than likely be ordered by model number and serial number of your unit.

The outdoor unit should have 2 small wires connected to the contactor coil. This delivers the 24v "Signal" to energize the coil. The wire from the t'stat for cooling are usually yellow, in almost every case. When you put the t'stat in the cooling mode and set the temp lower than the room temp, the indoor and outdoor unit should come on. Check for voltage on the terminal block for 24 volts accross the yellow and common wire. Common could be ground on some handlers. If you have the 24 volts, then check for 24v on the 2 small wires (usually 18 to 22 gage wire) on the contactor coil. If no voltage, trace the 2 wires back to the indoor unit and see where they go. If they are the ones that are not attached, put one on the yellow wire terminal and the other on the common terminal. This will send power to the indoor unit and then piggyback to the outdoor unit. Do not remove the yellow and common from the terminal block. Don't be too concerned about the colors from the outdoor coil wires. Just make sure they are hooked up right. Good Luck and hope this gets it going.

SOURCE: I HAD TO REPLACE THE CAPACITOR ON MT INTERTHERM A/C UNIT

Most common color codes are Yellow or Red from the H(herm) terminal of the capacitor to the compressor, Brown (sometimes with a white stripe) from the F(fan) terminal to the outside fan motor. Then Orange is usually a hot lead from the contactor to the C(common) capacitor terminal. Looking at the other outside fan wires you often see purple picking up power from the same C(common) capacitor terminal and a black wire going to the contactor output opposite of the orange wire... but of course that's the same as purple and black being on the two contactor outputs. Lots of contactors nowadays switch only one side, so be aware your fan is hot when not running and can short through a bad capacitor to ground and burn up the fan wires. Switching to a double pole contactor is easy to do but will disconnect the compressor warming element -- needed in cold climate areas. You'll know if you have this because there's 5 wires going to the compressor instead of 3 and the two smaller size black wires go to the contactor switched side so that they are OFF when the contactor is closed... and pull current to the heater through the motor circuit via the bridged side of the contactor when the system is not running. So if you want a system that's really off when the contactor is open you need to decide if the warmer is required and how to connect it via an additional relay that will be normally closed (NC). These can be purchased as add-on or bolt-on switches to fit on some contactors or buy a contactor with a normally closed switch -- in addition to the 2-pole switch for main functions.

Well, it sounds as if you have a Coleman rooftop unit. If you have a start capacitor with a PTCR (Postive Temperature Coefficient Resistor) then it is different than if you have a Potential Motor Starting Relay. Why are you replacing the run and the fan capacitor?

Here is a link to the documentation that you need. If you do not have a Coleman and it is in fact a Duo-Therm, let me know the model number and I will be able to pull up the wiring schematic.

Thanks,

It shows your model above. This is the only way to get a diagram for this unit. Please keep me posted on the out come or if you need more help.
