Owner’s manual
Can I replace AC spare parts myself?
Yes, you can replace some parts on your Goodman CK60-1 outdoor air conditioner and heat pump unit yourself, but we only recommend DIY work that stays outside the sealed refrigerant system and within your comfort level. For electrical and refrigerant-related repairs, use the wiring and service guidance in the CK60-1 owner's manual and consider professional service.
What you can usually do yourself (DIY-friendly)
- Replace a run capacitor if you can safely shut off power and label wires first
- Tighten loose electrical connections (only after power is fully off)
- Clean debris from the outdoor coil and base pan (gentle water, no pressure washer)
- Replace damaged wire terminals or insulation
- Inspect and replace a blown fuse in the disconnect (if your setup uses fuses)
A common DIY replacement on this model is the capacitor CAP050600440RTP.
What we do not recommend as DIY
These tasks can involve high voltage, specialized tools, or refrigerant handling:
- Compressor, condenser fan motor, or contactor diagnosis without proper testing
- Refrigerant leak checks, evacuation, or recharging
- Brazing/soldering refrigerant lines
- Control board troubleshooting beyond basic visual inspection
Quick safety checklist before you start
- Turn off power at the breaker and the outdoor disconnect
- Confirm power is off with a meter (not just the thermostat)
- Take a clear photo of wiring before removing anything
- Discharge capacitors properly before handling terminals
- Use insulated tools and keep hands clear of the fan blade
DIY decision guide
| Task | Typical DIY difficulty | Risk level | Best next step |
|---|---|---|---|
| Coil cleaning | Low | Low | Follow the cleaning steps in the manual |
| Run capacitor replacement | Medium | Medium | Match ratings and wire positions exactly |
| Refrigerant work | High | High | Schedule professional service |
Why it matters
On an outdoor condenser unit like the CK60-1, the wrong DIY repair can create repeat failures (miswiring, incorrect capacitor ratings) or safety hazards (shock, damaged compressor). Sticking to basic maintenance and clearly defined electrical replacements helps keep cooling performance stable and protects major components.
For parts ordering, use the parts list for your CK60-1, or search by model number on Sears PartsDirect.

How to tell AC tonnage by model number?
For Goodman model CK60-1, the “60” in the model number indicates about 60,000 BTU/h of cooling capacity, which equals 5 tons (60,000 ÷ 12,000 = 5). Confirm the exact rating on the unit data plate and in the CK60-1 owner's manual.
Quick tonnage math (works for most central AC model numbers)
Many outdoor condenser model numbers include a two-digit capacity code that represents BTU in thousands.
- Find the capacity code in the model number (often 18, 24, 30, 36, 42, 48, 60).
- Convert to BTU/h by adding three zeros (example: 36 = 36,000 BTU/h).
- Divide BTU/h by 12,000 to get tons.
- Round to the nearest common size (1.5, 2, 2.5, 3, 3.5, 4, 5 tons).
- If the model number does not clearly include a capacity code, use the data plate rating as the deciding value.
Common capacity codes and what they mean
| Model number code | Approx. BTU/h | Approx. tons |
|---|---|---|
| 24 | 24,000 | 2 |
| 36 | 36,000 | 3 |
| 48 | 48,000 | 4 |
| 60 | 60,000 | 5 |
Why it matters
Tonnage affects system matching (indoor coil and blower), breaker and wire sizing, and diagnosing issues like short cycling or poor cooling. When you order parts for CK60-1, knowing the capacity helps you stay aligned with the correct electrical and motor requirements.
Parts note for CK60-1
If you are troubleshooting hard starts, humming, or a fan that struggles to spin up, a weak run capacitor is a common cause. The listed replacement option for this model is the capacitor CAP050600440RTP (part number B94577500). Capacitors can hold a charge even with power off; follow the safety steps in the manual.

What is the average cost to replace a 3.5 ton AC unit?
Replacing a 3.5-ton central AC (similar capacity to many Goodman outdoor units like model CK60-1) typically costs $5,000 to $9,000 installed, with many homeowners landing around $7,500 for a mid-efficiency split system; your final price depends on equipment efficiency, labor, and any duct or electrical upgrades.
What’s included in that price range
Most installed quotes bundle the outdoor condenser, indoor coil (or air handler), refrigerant work, and startup.
- Removing and disposing of the old outdoor unit
- Setting the new condenser on a pad or stand
- Connecting refrigerant lines and pulling a vacuum
- Electrical disconnect, whip, and basic wiring connections
- System charge, test run, and airflow checks
Biggest factors that change the installed cost
These items move the price the most for a 3.5-ton replacement:
- Efficiency rating (higher efficiency equipment costs more up front)
- Refrigerant line set condition/length (reuse vs. replace)
- Ductwork condition (repairs, sealing, resizing, or replacement)
- Electrical work (breaker, disconnect, wiring, or service upgrades)
- Indoor equipment match (new coil/air handler vs. reusing existing)
Quick cost guide (typical scenarios)
| Scenario | What changes | Typical impact on price |
|---|---|---|
| Straight swap | Existing ducts and electrical are usable | Lower end of the range |
| New indoor coil/air handler too | More parts and labor | Mid range |
| Duct or electrical upgrades needed | Additional materials and time | Upper end of the range |
Why it matters
A 3.5-ton system is a major electrical and refrigerant appliance; correct sizing, matched components, and solid installation practices protect comfort, energy use, and compressor life. For model-specific specs and service information, use the CK60-1 owner's manual.
If you’re repairing instead of replacing, common no-start and weak-cooling complaints can involve electrical components like a run capacitor; you can look up the capacitor CAP050600440RTP for this model, or search by model number on Sears PartsDirect.

What is the average lifespan of a Goodman AC unit?
A Goodman central AC outside unit like model CK60-1 typically lasts 12 to 15 years. With correct installation, clean airflow, and yearly maintenance, many units reach 15 to 20 years before major components (compressor, condenser fan motor, capacitor) start failing more often.
Typical lifespan ranges (what to expect)
Most central air conditioner and heat pump outdoor units fall into these ranges:
| Condition | Typical lifespan | What usually ends the unit’s life |
|---|---|---|
| Average use, basic maintenance | 12 to 15 years | Compressor wear, refrigerant leaks, electrical failures |
| Good installation, annual service | 15 to 20 years | Compressor or coil failure, repeated electrical issues |
| Harsh coastal or extreme-heat environment | 10 to 14 years | Corrosion, high run time, coil damage |
What makes a Goodman AC last longer
We see the biggest lifespan gains when these basics are handled consistently:
- Keep the outdoor coil clean and unobstructed (leaves, cottonwood, grass clippings)
- Replace or clean indoor air filters on schedule to protect airflow and pressures
- Maintain proper refrigerant charge (low charge drives high run time and stress)
- Tighten and inspect electrical connections during annual service
- Replace weak electrical parts early (a failing run capacitor can damage motors)
Quick signs your unit is nearing end of life
These symptoms often show up more frequently after the 12 to 15 year mark:
- Hard starting, humming, or frequent breaker trips
- Outdoor fan runs but cooling is weak or inconsistent
- Longer run times and rising energy bills
- Repeated service calls for electrical or refrigerant issues
- Loud compressor noise or vibration
Why it matters
Knowing the expected lifespan helps you decide whether to repair or plan a replacement. For example, replacing a common wear item like a run capacitor is often a smart repair, especially if the system is otherwise cooling normally.
Parts that commonly affect reliability
- Capacitor CAP050600440RTP (part number B94577500): helps the compressor and fan motor start and run correctly
