Your "R" terminal is basically your "hot" and your "C" terminal is basically your "neutral" to simplify explanation. The Furnace supplies the "R" power to the thermostat and then depending on what wire the thermostat sends the power back on determines what the system does. The thermostat terminals are as follows "G" is fan, "W" or "aux" is elect heat, "Y" tells the outdoor unit to run, "O" or "B" tells the outdoor unit whether it is heating or cooling, and "E" is emergency heat. "G" should connect from the t-stat directly to the furnace and go no further. "W" or "aux" AND "E" should both connect to your "W" or "W1" terminal in the furnace, there should also be a "W" connection to the heat pump ( this allows the H/P to turn on the elect heat when the unit defrosts) "Y" and "O" or "B" may or may not connect to a terminal in the furnace, usually they just pass through the furnace from the t-stat to the H/P and get wire nutted in the furnace. Now, here is the key. As I mentioned previously "O" or "B", a system will only use one or the other. The entire industry (except for Rheem and Ruud) uses the "O" terminial which has 24v on it when you are cooling and no power when you are heating. Rheem and Ruud use the "B" terminal which is just backwards, 24v in heating and no power in cooling. This is all for a heat pump, If you do not have a heat pump, then disregard the references to "O", "B", "E", and "aux". You will have R-power on red wire, W-heat signal to furnace, G-fan signal to furnace, and "Y" cool signal to outdoor unit.

SOURCE: ac will not turn on, ac clicks but does not turn on

At this point, you have to check to make sure that none of the wire became dislodged in the t-stat. If all the wires are securely connected, check to be sure that you are reassembnling the t-stat correctly.

If all is well at the t-stat, then the next step is to start testing the HVAC components; you will need a voltmeter for this step

SOURCE: Ruud Achiever 10 heat pump - outside fan won't shut off

Definately get this checked out. Some thing has shorted just enough to let voltage "Feed back" and keep the fan running. Could be capacitor, wires rubbed through each other, etc. A reset is a safety that is used when there is an overcurrent or over pressure situation. No reset set for this situation.
There is always an outside chance that if you touch the unit while standing on wet ground, you may get shocked. I firmly believe that something is allowing power to the fan in a feedback condition so don't let this go as it may cause damage to other parts.

Good Luck and let me know how you make out on this.

SOURCE: Ruud AC fan won't shut off

it sounds like this is an electromechanical system, (no circuit board) verify that you wired the normally open switch at the fan limit control to the low speed fan, to the normally closed on the relay..(series circuit) if either of these are wrong the fan will runn all the time

Display says battery power ac not working


you have lost control power from the unit, either line voltage/breaker tripped, or low voltage from control transformer which may have a blown fuse and a short in the control wiring to the thermostat

Rudd thermostat says battery power


Most new digital thermostats are design to run with battery or A/C power, unless the A/C power is connected to the thermostat via a connection to the common "C" connection to the furnace common the thermostat defaults to battery operation and that is normal. Batterys last from 3 to 5 years in the average thermostat.

I have a RUUD Furnance with a piolet light. There


If you have a pilot, then this is an older furnace. Most of them use a 2 wire thermostat. Allot of the new digital, programmable thermostats require a 3rd wire - a common to the thermostat. Allot of old furnaces do not have a common terminal on the furnace board. It can be done, but takes a good technician. The way around this is to use a digital, programmable thermostat that will operate on straight battery. It will be stated on the thermostat package, saying it will operate with a common wire from the furnace or with only the use of the batteries.
Then make sure that you hook up the 2 wires to the "R" terminal and one wire to the "W" terminal, it doesn't matter which thermostat wire goes to which terminal.
Note: If you have a air conditioner installed, it will be a different story.
Sincerely,
Good Luck,

Nikon L100 shows battery exhausted error message after installing new batteries. Unable to perform any operations on camera


That's the bug in Nokin L100, update the firmware version from 1.0 to 1.1, this will solve the battery exhaust problem. Firmware version 1.0 has only 2 battery (Alkaline and Lethium) option where as Firmware version 1.1 has Nickle battery also. But, to update the firmware you need to have EH-67 AC Adapter to give power to the camera.

Have a Ruud AC unit the problem I have after installing a new condenser fan motor when I throw the circuit breaker the unit will not turn on but when I push the contacts on the contactor in manualy the fan...


The contactor engages from low voltage power from the thermostat as does the outside condensing unit. You may have blown the low voltage transformer or have a loose thermostat wire. Check line voltage(220 volts) to the transformer. Check load voltage(24 volts) from the transformer. If no voltage out,replace the transformer. If you have voltage out(24) check the thermostat wires and the thermostat. If you have a digital thermostat there is a 5 minute delay in the thermostat after power is restored before it activates.

Thermostat message battery low. Put in two new batteries and it will not reset or start. Lost Power during storm and cannot get it going again.


Let me see if I understand your question.. your thermostat indicated the batteries needed to be replaced so you changed them with new ones.. With new batteries, you cannot get your thermostat to initialize or program correctly and as a result of that, you cannot get your AC system to start up.. If that is true, please provide the Honeywell Model # and verify the batteries you installed were Ok,...
Will attempt to assist once you've provided this info..

( on an off chance, have you checked the fuse or cuircuit breaker for your AC system to make sure it has power available?) This is especially important after a power outage..

I changed the filter on my ruud 1x2000 the other day did not try to turn on until yesterday.tried ac nothing then tried heat nothing. changed termastat still nothing.


is this a whole house air conditioner ,
if so check the fuse panel,
check to see if the outside unit runs at all , compressor or fan.
check the ac transformer power to the thermostat
check the switch in the ac closet
doe the internal fan run if you switch to fan only.
