Question about Specialty Electrics
I have a white control box under my heating control box on the wall, which has three buttons on it....DSI Indicator, Summer Fan, and Economy. These buttons used to light up but dont anymore, so I am wondering what could have happened, and how to use them if they do still work?
I've had a central heating expert(?) to service the unit last winter, but he had no idea what the buttons meant, and promised to find out but never got back to me! Have a feeling he may have turned off the control box under the house when he was servicing the unit, because it hasnt lit up since.
Any help or suggestions, or even an idea where to get a manual would be great,
thank you in anticipation,

a simple capacitor tester will tell if the capacitor is bad. turn off power, label wires and where they go and test cap after discharging it . to discharge simply connect the terminals together once its been removed( you can use an insulated screwdriver to connect them and discharge any stored voltage) and then touch meter leads to each set of terminals and read the microfared output. the setting on the meter is usually labeled uf. or you can take it to the electric motor shop and let them test it. it has a rating value labeled on the side. usually it has to be within 10 percent of the rated value or its bad . if the cap checks good then the start winding in the motor is probably bad or weak, then a new motor is called for, it is usually not worth the time wait and trouble of getting it rewound etc. take the old motor out and label and measure exactly how and where it was mounted. label and make diagrams. saves a lot of time reassembling exact as it came out. turn off the power , check it with a meter to be sure , short it with a screwdriver to be sure the meter works ,and then treat it as if it was still hot as much as possible when you work on it.

It sounds like the direction switch has a broken connection on the "reverse" side. Should be an easy fix (but you might need a soldering iron).

Hello, W/D here. It sounds like you have bypassed your on/off switch.
The white wire is the common wire, which returns the power to ground, and completing the circuit. By connecting this wire, you have completed a circuit, indicating that power was constantly on to the fan.
Gain access to your wiring in the ceiling (trip the breaker first, please).
If you have tied your hot wires to a twisted bundle of black wires, you have tied to the hot thru line. Look for a single black wire. What normally happens with the ceiling wiring is that the circuit hot wire goes to your ceiling box. Another wire connects to this one. It passes on to the next device on the circuit. Yet another wire ties to the bundle. It is your switch hot wire. It goes to the switch, and returns to the ceiling box. The return wire from the switch is the one you're looking for.

Try to move the clock to a different place. Atomic clocks work by receiving a radio signal. If it has no reception, it may do that. However, I would suspect that no reception would lead to it not setting at all(at least based on the ones I've seen) and it may be something wrong with it (i.e. having difficulty detecting where it's hands are) Good luck.

Here is the part you are referring to:
The cord should be connected on the backside of the blower. If not, you need another or replace the whole blower. Hope this helps.
