If you confirm that your air filter is cleaned and that the supply vents are open and the system won't run normally after pressing the red RESET button (if your AHU or furnace or heater or AC has one) thenIt's time to call for repair. He claims this is not a problem but that the board may need changed in the future. I turned the unit off and waited a while. (Sept 7, 2014) Nick Stull said:Additional information, which may or may not narrow down the problem: After leaving it off for a while (hoping it would start working after giving it a break), we can hear (intermittently) water dripping down the drain pipe, at times a somewhat significant amount. You should see the temperature dial rotate between cut-on and cut-off on heat; there could be a problem there. 0000008849 00000 n

Sometimes there's also a pump that should be checked. Look for a refrigerant leak, low refrigerant, ice-clogged cooling coil. The enabling of this feature adds a means to prevent low or high supply air temperatures from being delivered to the conditioned space.If you don't have the service manual we can help you find one.

Air is cool coming out of vents, but not cold. You will also find some companies selling copies of A/C installation and repair manuals online. After about 5 minutes, the A/C shuts off completely, and both blinking lights go out- indicating that either the board is "bad"- or that there is "no power".

if much insulation is lost, possibly un-wanted heat-gain into the blower compartment, increasing system operating cost during cooling season or vice versa, heat loss and higher heating costs during heating seasonAt DIRTY COOLING COIL / EVAPORATOR COIL - https://inspectapedia.com/aircond/Clogged_Evaporator_Coil.php we describe a blocked coolign coil and several problems that occur if insulation falls onto the cooling coil surfaces - on your system that might not be in the same area as the damage you describe.I wouldn't sweat a trivial nick or an inch of disturbed material but if the insulation is missing entirely over parts of the blower compartment or is loose enough to get drawn in I'd have it replaced. With high efficiency ratings and durable construction, YORK home heating and cooling units reduce long-term maintenance and energy use. In VAV systems, the supply air temperature, as well as the supply air volume, are continuous functions of zone air temperature. After all the thermostat is simply an on-off switch.
