Most likely you've already figured out that the problem is with your backup heat system - which kicks in when the heat pump can't extract enough heat from the outdoor air. What's going on? One person came and changed the compressor . The enabling of this feature adds a means to prevent low or high supply air temperatures from being delivered to the conditioned space. Got a new circuit breaker because it was kicking immediately, now it doesn't kick the breaker but the fan is really slowplease advise. 0000009700 00000 n 3468 0 obj <>stream change of approx. 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? 0000006432 00000 n unit not putting out cold air. 0000010035 00000 n 0000027434 00000 n CKL, CLJ, CRT, CLT, TWC, CLQ & HDC Compressor overheating. 0000011504 00000 n 0000013639 00000 n From just your note, AC, I can't make a useful guess. 0000038721 00000 n I just down sized unit to 2.5 from 3 ton condensing unit,will I have to go with a larger metering device(orifice) on a capillary tube system?

Ended up changing the compressor/fan capacitor and the contactor circuit board. 0000005980 00000 n 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. (Jan 5, 2015) George Kubo said:Heat Pump fan comes on when you turn on the thermostat for heat but goes off after a minute. He claims this is not a problem but that the board may need changed in the future.

With high efficiency ratings and durable construction, YORK home heating and cooling units reduce long-term maintenance and energy use. At that time we had a cold-snap and I had to turn my heat back on. 0000013777 00000 n The performance testing standards for air-source heat pumps are CSA C656, which (as of 2014) has been harmonised with ANSI/AHRI 210/240-2008, Performance Rating of Unitary Air-Conditioning & Air-Source Heat Pump Equipment. there is no effect on the compressor unit.

But as you can read in Pete's comments above, another explanation for an A/C unit that cycles between blowing cool then warm air can be a contol problem that is switching the emergency backup heat on - IF your system is a heat pump. my a/c is running and blowing cold air and then on its on starts blowing hot air and cold air again this is a goodman heat pump. 0000015584 00000 n Is he yanking my chain? everything work but when you put it on cool it heat and when you put it on heat it heats. knowledge is power. 4-4 - Example of Fc Fan Shaft/Wheel Marking, Fig. endstream endobj 3247 0 obj <> endobj 3248 0 obj <> endobj 3249 0 obj <>stream Walk through the following furnace and air conditioning troubleshooting steps to diagnose and address the most common HVAC system issues.
