Heat Pump Not Working: Youtube Videos

Quick answer

If your heat pump isn't working, first check the thermostat settings and ensure the power is on. Clear any debris from the outdoor unit and replace the air filter. If it still doesn't work, watch the videos below for more troubleshooting steps.

Confirm the symptom

• Heat pump won't turn on.
• Heat pump blows cold air in heating mode.
• Heat pump blows warm air in cooling mode.
• Heat pump makes unusual noises.
• Heat pump frequently cycles on and off.
• Ice buildup on the outdoor unit.

Tools and prep

• Screwdriver (flathead and Phillips)
• Multimeter
• New air filter
• Garden hose
• Safety gloves and glasses
• Ensure power is off at the breaker box
• Clear the area around the outdoor unit

Step-by-step troubleshooting

1. Check Thermostat Settings
   Do: Ensure the thermostat is set to the correct mode (heat or cool) and the desired temperature.
   Observe: If the settings are correct, proceed to the next step.
   Means: Thermostat issue ruled out.
   Next: Check the power supply.
2. Check Power Supply
   Do: Ensure the heat pump is receiving power by checking the breaker box and the outdoor unit's power switch.
   Observe: If the power is on, check the next component.
   Means: Power supply is not the issue.
   Next: Inspect the air filter.
3. Inspect the Air Filter
   Do: Locate the air filter and check for dirt or clogs. Replace if necessary.
   Observe: If the filter is clean, move to the next step.
   Means: Air filter is not the problem.
   Next: Clear debris from the outdoor unit.
4. Clear Debris from Outdoor Unit
   Do: Remove leaves, dirt, and other debris from the outdoor unit using a garden hose.
   Observe: If the unit is clean, proceed to the next step.
   Means: Debris is not the issue.
   Next: Check the refrigerant lines.
5. Check Refrigerant Lines
   Do: Inspect the refrigerant lines for ice buildup or leaks.
   Observe: If there is ice buildup, defrost the unit according to the manufacturer's instructions.
   Means: Refrigerant lines may need attention.
   Next: Test the capacitor.
6. Test the Capacitor
   Do: Use a multimeter to test the capacitor for continuity.
   Observe: If the capacitor is faulty, it needs to be replaced.
   Means: Capacitor issue identified.
   Next: Replace the capacitor if necessary.
7. Replace the Capacitor
   Do: Follow the manufacturer's instructions to replace the capacitor.
   Observe: If the heat pump still doesn't work, consult a professional.
   Means: Capacitor replaced successfully.
   Next: Call a professional if needed.

Common causes

Parts matching

When troubleshooting your heat pump, you may need to replace certain parts. Here are some common parts to check:

• Capacitor: Helps start the compressor and fan motor.
• Air Filter: Ensures proper airflow and efficiency.
• Refrigerant: Essential for heat transfer.
• Thermostat: Controls the temperature settings.
• Coils: Transfer heat between the indoor and outdoor units.
• Compressor: Circulates refrigerant through the system.

Always ensure you have the correct part number and model compatibility before purchasing replacements.

When to call a professional

• If the heat pump still doesn't work after troubleshooting.
• If you suspect a refrigerant leak.
• If the compressor is faulty.
• If you are not comfortable performing the repairs yourself.
• If the issue persists after replacing common parts.
• If there are electrical issues beyond your expertise.
