Amana PHK105/P9828101C package unit with accessories - spco series Parts

For your Amana PHK105 package unit (SPCO series), the right AC spare parts are the ones that match your exact model and the exact function you are repairing (cooling, heat, blower, or controls). Start by confirming the model number on the rating plate, then match the part by description and application before ordering from Sears PartsDirect.

• Confirm the model number is PHK105 (rating plate is typically on the cabinet or inside an access panel).
• Identify the system section you are repairing: compressor circuit, condenser fan, indoor blower, heat kit/accessory, or control wiring.
• Use the symptom to narrow the part type (for example: no cooling often points to capacitor, contactor, or fan motor issues).
• Match by part description and application, not just “looks similar”.
• Compare electrical ratings when applicable (voltage, microfarads for capacitors, coil voltage for contactors, amp rating for fuses).
• Replace related wear items together when it makes sense (for example, a weak capacitor can damage a fan motor over time).

Central air conditioner parts are not universal. A “close” match can cause hard starts, blown fuses, short cycling, poor airflow, or compressor damage. Matching the part to Amana PHK105 keeps the system safe, efficient, and reliable.

• Shut off power at the disconnect and breaker before opening panels.
• If you are diagnosing electrical issues, use a meter correctly and safely; see how to use a multimeter to test electrical parts video.
• If you suspect a fuse issue, confirm it properly; see how to tell if a fuse is blown.

For the Amana PHK105 package unit, the most commonly replaced AC parts are the run capacitor, contactor, condenser fan motor, blower motor components, and air filter related items; these parts handle frequent starts, electrical load, and airflow, so they wear faster than the sealed refrigerant system.

• Run capacitor: Helps start and run the compressor and fan motors; a weak capacitor can cause hard starting or humming.
• Contactor (relay): Switches high voltage to the compressor and condenser fan; pitted contacts can cause intermittent cooling.
• Condenser fan motor: Moves air through the outdoor coil; failure often shows up as overheating and shutdowns.
• Blower motor or blower components: Moves conditioned air through ductwork; problems show up as weak airflow or icing.
• Air filter and airflow-related items: A clogged filter can trigger coil icing and poor cooling.
• Fuses (in the disconnect or control circuit): Can open during electrical faults or surges.

These components cycle on and off, carry electrical load, and depend on clean airflow. Heat, vibration, and dust make capacitors, contactors, motors, and filters the most frequent service items on central air conditioner systems like the Amana PHK105.

• Turn off power at the disconnect and breaker before inspecting anything.
• Replace the air filter and clear debris from the outdoor coil area first.
• If you suspect a fuse or capacitor issue, test with a meter rated for HVAC work.
• Confirm the exact model and any revision details from the unit data plate.
• Match electrical ratings (voltage, microfarads, amperage) exactly when selecting electrical parts.

A central AC system is made up of controls, refrigeration components, airflow components, and safety/electrical parts that work together to move heat out of your home. For an Amana PHK105 package unit, many of these components are housed in one outdoor cabinet.

• Thermostat: calls for cooling and controls system operation.
• Evaporator coil: absorbs heat from indoor air.
• Condenser coil: releases heat outdoors.
• Compressor: pumps refrigerant through the system.
• Metering device (TXV or fixed orifice): regulates refrigerant flow.
• Blower/air handler section: moves air across the evaporator coil and through ductwork.
• Ductwork and registers: deliver and return air through the home.
• Refrigerant lines and refrigerant: carry heat between coils.

• Contactor/relay: switches power to the compressor and fan.
• Run capacitor(s): helps start and run the compressor and fan motor.
• Transformer: steps voltage down for control circuits.
• Control board (on some units): manages timing, safeties, and diagnostics.
• Pressure switches and limit switches: protect the system from unsafe conditions.
• Fuses or breakers: protect wiring and components.

Knowing the major components helps you narrow down whether a problem is airflow (filter, blower, duct restriction), refrigeration (coil/compressor/refrigerant), or electrical (capacitor/contactor/fuse). That makes troubleshooting faster and helps you order the right replacement part.

• Replace or clean the air filter (restricted airflow can mimic bigger failures).
• Confirm the thermostat is set to Cool and the temperature is set below room temp.
• Check the outdoor disconnect and electrical panel for a tripped breaker.
• Look for a non-spinning condenser fan (often capacitor-related).
• If you suspect an electrical issue, use safe testing practices; our are diy appliance repairs safe guide helps you decide what to DIY.
• When you are ready to shop, search by model number PHK105 on Sears PartsDirect.

For an Amana PHK105 central air conditioner package unit, AC spare-part prices range from under $10 for small electrical items to $3,000+ for major sealed-system components (like a compressor or coil). Your exact price depends on the specific part, electrical ratings, and whether it is an exact match for PHK105.

Use these as planning ranges; we always recommend pricing by model number and part description on Sears PartsDirect.

• Fuses, connectors, screws, terminals: $5 to $25
• Run capacitor / start capacitor: $15 to $80
• Contactor / relay: $20 to $120
• Pressure switch / limit switch: $25 to $150
• Control board (if equipped): $120 to $600
• Condenser fan motor / indoor blower motor: $150 to $700
• Compressor or coil: $800 to $3,000+

These details change pricing and compatibility the most on package units like the PHK105:

• Electrical specs (voltage, amperage, microfarads on capacitors)
• Motor specs (HP, RPM, rotation, shaft size, mounting)
• System design (single-stage vs multi-stage controls, heat kit accessories)
• Age and availability (older units can have fewer direct replacements)
• Repair category (electrical vs sealed-system work)

Most central air conditioner repair decisions come down to total cost (parts plus labor). Lower-cost electrical parts can restore cooling quickly, while compressor or coil repairs are major investments and should be weighed against overall system condition.
