About This Lennox Heat Pump
The model designation on this unit breaks down directly into its key specifications: the X indicates R-410A refrigerant, the P marks it as a heat pump outdoor unit, the 14 refers to the SEER efficiency tier, and 036 identifies the 3 ton nominal cooling capacity within the Elite XP14 lineup, which spans from 1.5 to 5 tons across that same numbering pattern. Because this is a heat pump rather than a cooling only condenser, it runs during both summer and winter, which roughly doubles annual compressor and fan run hours compared to an air conditioner covering the same square footage, and it relies on a reversing valve, a component not present on cooling only equipment, to switch refrigerant flow direction between heating and cooling modes. Lennox pairs this outdoor unit with matched CBX or similar indoor coils, and confirming the full model and minor revision suffix helps ensure a capacitor or control component is rated for the correct voltage and capacity. This heat pump carries a 10 year limited warranty on the compressor and a 5 year limited warranty on other covered components in residential installations, provided the unit is registered online within 60 days of installation. It uses a single phase power supply and a vertical air discharge pattern that allows the outdoor unit to be tucked behind shrubs at grade level or installed on a rooftop with minimal visual impact. Because it is designed to pair with a remotely located indoor air handler or a gas furnace fitted with an add on coil, a dual fuel compatible thermostat or zone control system is required whenever this heat pump is paired with a gas furnace rather than an electric air handler. Scheduling a professional tune up each spring and fall, in addition to routine filter and coil checks a homeowner can handle personally, helps catch small refrigerant or electrical issues before they turn into a costly compressor failure. Keeping shrubs, leaves, and yard debris cleared from around the outdoor unit maintains the airflow the condenser coil needs to operate efficiently in both heating and cooling modes throughout the year. A homeowner can safely check that the outdoor coil fins are not visibly bent or clogged with debris, though any work involving the refrigerant circuit itself should be left to a licensed, EPA 608 certified technician. Because this equipment cycles on in both winter and summer, an electrical connection that loosens over time from vibration is more likely to show up as an intermittent fault than it would on cooling only equipment. Rinsing the outdoor coil gently with a garden hose once or twice a year, with power to the unit disconnected first, removes pollen and airborne debris that gradually restricts airflow across the fins. Confirming the outdoor unit sits level on its pad also matters over time, since a unit that has settled unevenly can place extra strain on refrigerant lines and electrical connections at the base of the cabinet. Replacing the indoor filter on schedule protects more than just airflow, since a severely restricted filter can eventually cause the indoor coil to freeze, which in turn reduces heating and cooling output system wide.

Most Replaced Parts on the XP14-036-230-1
Capacitor Testing on the XP14-036-230-1
A compressor that hums but does not start, or an outdoor fan that spins slowly, points to a weak or failed dual run capacitor. Match all microfarad values printed on the capacitor label exactly when ordering a replacement, and test capacitor readings before each cooling season and again before each heating season, since this unit runs compressor hours in both modes.
Contactor and Electrical Problems on the XP14-036-230-1
If the outdoor unit does not respond at all to a thermostat call, pitted or stuck contactor points can prevent power from reaching the compressor and fan motor. Inspect the contactor points for burning or pitting before assuming the compressor itself has failed, since a bad contactor is a far less costly repair.
Fan Motor Issues on the XP14-036-230-1
A condenser fan that runs slowly, makes grinding noise, or fails to start while the compressor still runs usually points to a worn fan motor bearing or a failed run capacitor feeding that motor. Confirm capacitor readings before replacing the fan motor outright, since a weak capacitor alone can mimic motor failure.
Reversing Valve Problems on the XP14-036-230-1
If the system blows warm air while set to cool, or cold air while set to heat, a reversing valve stuck in one position is a likely cause specific to this being a heat pump rather than a cooling only unit. Test the reversing valve solenoid coil for continuity before replacing the valve body itself, since a failed solenoid is a simpler and less expensive repair.

- Seasonal capacitor testing guidance: Because this is a heat pump rather than a cooling only unit, our repair help recommends testing capacitor readings twice a year, once before each heating season and once before each cooling season.
- 365 day returns: Order with confidence knowing every part is backed by our 365 day, no hassle return policy and expert customer support.
XP14-036-230-1 Parts FAQ
What size and refrigerant does this heat pump use?
It is a 3 ton, R-410A heat pump from the Elite XP14 series, rated up to 16 SEER for cooling and paired with a matched indoor air handler or furnace coil.
Why does the system blow warm air in cooling mode?
A reversing valve stuck in heating position is a common cause on this heat pump. Test the solenoid coil for continuity before replacing the valve body.
How is this heat pump different from a cooling only condenser?
It contains a reversing valve and runs during both winter and summer, roughly doubling annual compressor and fan hours compared to an air conditioner covering the same space.
How often should the capacitor be tested?
Test it twice a year, once before the heating season and once before the cooling season, since this heat pump runs the compressor year round rather than only in summer.
