Ruud central air conditioning and heat system

The problem start almost two months ago. I turn on the acc at night and i set the termosthat at 67, it never stop runinng , so at 61 y turn the thermostthat off, nothing happen, so i turn off the power on the unit.with the termostat off, if I turn the power on the blower start. Couple of days ago we try the heat system,so i moved the termosthat to heat and i set to 71,the circulating pump star ok, the boiler after 3 minutes ok. I turn on the power on the unit when the coil was hot, at the same time the condenser for the acc start also, so i removed the breaker outside for the unit, i wait until the temperature reach 72 i heard the click from the solenoid inside the termosthat, the boliler turn off and the circulating also, but the blower keeps runinng. I changed the termosthat, nothing happen. i removed all the wires conected to the termosthat and the blower keeps runing . The system was working fine before so any any help would be great

I have a RUUD central air conditioning system, model NBHC-18J20SFA. The cooling function is not working. The fan on the outdoor unit is not working. When switching to COOL, the compressor works for a few...


sounds like the outdoor fan motor and/or capacitor needs replaced. The compressor will run for a short time because the fan is not pulling the heat out of the system, it can cause damage to the compressor if the fan is not repaired, Ruud used a 3uf capacitor rating for the outdoor fan motor, if the motor has been changed make sure the proper capacitor is also changed for the new motor rating.

Central air conditioning system is blowing warm air.


many, many. Is the outside unit running? If it is, is the compressor running? Feel the refrigerant lines leaving the unit. Little one should be warm. Big one should be cold, probably sweating.

I had a 14 seers Trane installed 18 months ago. The thermostat goes blank and the system doesnt come back on until I flip the breaker or disconnect power to the ac.


try replacing the batteries in the thermostat on your wall. probably has 2 AA's this may fix it if not may have bad or old wiring from tstat to main indoor system. when you had a trane installed did they change the air condition components only(likely) or did they put in new furnace, new wiring, new t-stat, a full install?

Heat not blowing on heat cycle


Have to know what kind of heat it is, Gas, Electric or Electric Heat Pump.

Heat pumps, when air over air type, have an extra setting on the thermostat labeled Emergency Heat, Although these thermostats can work on the other types of heating as well.

Both modern Gas and electric furnaces have the blower controlled by a blower board. The flame and or heating elements can also be controlled by the same or a separate board. SO you could have a board problem, or a safety switch or other symptom causing a safety switch to trip off on you.

Consult with your diagram and find something you can recognize then trace the wires down and follow to where you get the power to turn on the heat (usually always R feeds thermostat and W feeds Heat). Colors of the attached wires means nothing at this point. Look for the terminal designations not colors.

Hope this helps you. Please grade me accordingly and GOOD LUCK. :)

Furnace runs on heat, air conditioner does not


If you have a Gas furnace in the Attic then the answer is yes. The outside condenser will not run if in fact you have a gas furnace.

My central ac system occasionally runs too long and the temperature gets way too cold. The digital thermostat reads that the temperature is too high so the ac still runs. This doesn't happen all the time...


I have seen this is many digital thermostats. The worst problems usually come from the touchscreen thermostats. I would suggest installing a new thermostat. Make sure that you read the instructions before you even remove the old one.
