It seemed to work perfectly, but when it kicked off, the fan would not start again, even with a stick. when I turned the unit on "cool", it started right up. Mauro up, you are describing a special feature on some York systems. We have checked most of the duct work, but some of it is not visible. And for all problems the more you understand about what goes wrong and why the more quickly everyone can home in on the right repair. We have a Honeywell RTH6350D programmable theromstat and changed the fan from auto or on and even that is not working. 0000007710 00000 n
I don't know,Gary, but often when weather switches a heat pump over to backup heat we find operating defects in the backup system that were there for a long time but never evident because the backup wasn't in use. Many A/C system air handler units include a condensate overflow pan switch that will sense a rise of water in the condensate pan and shut off the air handler unit. Found problem. Turn power off to unit being serviced or worked on. Ended up changing the compressor/fan capacitor and the contactor circuit board. But even if it was ice clogging the cooling coil, that would only indicate another set of issues it could be, among which would be either low or leaking refrigerant, right? As long as the room device is calling for cooling or heating the compressors or heating section does not control the actual temperature of the supply air leaving the unit. Replaced and is working. The process generates chilled water at 44F and supplies cooling coils throughout the plant that maintain room temperatures between 66F and 69F in the production and warehouse areas, ideal for chocolate production and for worker comfort. 0000014239 00000 n
To avoid an overheated circuit and possible fire. In that case you may be able to set the valve to perform properly.

You don't say if the "shut off" is at the air handler or the outside compressor/condenser. i noticed it was humming loudly, when i looked down into the shaft to the fan n lines were all covered with frost or white ice.

If the outside heat pump unit is not turning on there may be a failed control, relay, or even thermostat wire connection. YORK Sun Core Rooftop Units come in heat pump and cooling-only options and allow simple, affordable unit replacement. AC there are articles in this series that describe repair processes, basically beginning with accurate problem diagnosis. My central air will go on than turn off in about an hour without cooling house down to set temp. 20122023, manualsdir.comAll rights reserved. The proper repair is to clear the blocked condensate drain. Your tech says that the condensate drain line was plugged on your system. I really would like to get one more season out of the unit. Also check for low voltage. I would shut this system off. Thermostat (Honeywell) does not ignite the AC or fan or heat - but it could not possibly be the thermostat as the person who shut off the fan switch - also turned off the water heater. This explanation from the service manual should help. Noticed more frequently as outside air temperatures got cooler. So perhaps there is a thermostat or control problem that is shutting off the compressor, OR the coil is icing up. 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. or a loose fan blade hitting something? I'd give your service company a call. The local climate affects the temperature of the cooling water and air. If you don't have an installation and operation manual for your thermostat you (or we) ought to be able to find one, at no cost, by seaching for it based on brand and model number.

Can I repair it at home? Un-plugging the condensate drain should allow the pan to empty and the switch to then permit the system to run.

said. I live in Florida and it has been about 90 degrees lately, and my house (inside) has been about 85! the unit is only 5 years. If the return air temperature is raised 5F, and the temperature drop across the indoor coil is kept at 20F, the supply air temperature will go up 5F. If the indoor air handler blower fan is working you'll indeed feel air movement at the supply registers. The existing 3 ton blower and heater unit were reused. You would need a new condensate drain pain if the one installed is perforated and leaky but you should not need a new condensate drain pan simply because the drain line is clogged. later handed me a bill for 172.50 had I known I could have done it myself.
