Reset Button Not Working? Heat Pump Repair Tips
Has your heat pump's reset button stopped restoring normal operation? Pressing this button should restart the system and fix issues like a stuck thermostat setting. But if the reset button fails to pop back up, it likely indicates a deeper problem. Before calling an HVAC technician, try these troubleshooting tips to get your heat pump reset button working again.
Locating the Mysterious Reset Button
First you'll need to find the actual reset button on your outdoor heat pump unit. Check your owner's manual - the location can vary. It may be hidden behind a panel or recessed into the side. If no manual is available, inspect along the sheet metal exterior carefully. The button is often red or blue. It should be labeled "reset."
Using the Manual to Pinpoint the Button
The owner's manual for your specific heat pump make and model will call out exactly where the reset button is located. Don't skip this step! Reset buttons can be tucked away in different spots depending on the manufacturer.
For example, Carrier heat pumps often have the reset button along the top. Trane units may have it behind the exterior access panel. Goodman heat pumps tend to position it on the side of the cabinet.
When No Manual is Available
If you don't have the original owner's manual, check the manufacturer's website for a digital download. Alternatively, visually inspect the unit. Peer behind any removable panels. The button may simply be recessed into the metal siding.
Look for a colored button labeled "reset" on the sides or top. It's often red, blue, or yellow. The reset button is frequently near service ports and the model number tag.
Pressing in the Reset Button
Once located, you can press the heat pump reset button. Make sure the system is powered off for safety. Use a thin object like a paperclip to push it in completely. Hold for 5-10 seconds before releasing.
Materials Needed
Gather a few supplies before resetting the heat pump:
- Something thin like a paper clip to press the button
- A flashlight to see the button
- The owner's manual for reference
Power Down First
Shut off power to the heat pump at the breaker before resetting. This prevents electrical shocks. If you have a gas furnace paired with the heat pump, shut it off too.
Push Steps
Use your paperclip to firmly push in the reset button until it clicks. Maintain pressure for 5-10 seconds. Release the button - it should pop back out.
Avoid tapping or quickly jabbing the button. One continuous press is best.
Confirm Reset Took
Turn the breaker back on. The heat pump should power up as normal. Check your thermostat settings are as expected after a reset. Monitor heating and cooling performance.
A Stuck Reset Button
If the reset button fails to return to its raised position, this indicates a problem. Do not keep pressing it. Here's how to troubleshoot a stuck heat pump reset button.
Signs of a Stuck Button
After pushing in the reset button, it should pop back out when released. Signs of a stuck button include:
- Button stays depressed
- Clicks but does not unlatch
- Takes force to push in
Safety Concerns
A stuck reset button could mean electrical issues. Do not try to force or continuously press it. This could shock you. Call an HVAC technician for assistance.
Causes of Failure
Reasons why the reset button may get stuck and not pop up include:
- Faulty wiring
- Electrical short
- Power surges
- Old and worn button
Ruling Out Power Problems
Before assuming the button itself has failed, check for power supply issues. Verify the circuit breaker is on. Inspect fuses. Test outlet voltage. A voltage problem could prevent the reset.
Professional Repair Needed
If power supply checks out but the reset button remains depressed, call an HVAC technician. They can determine if wiring repairs or full replacement is needed.
Resetting vs. Repairing Your Heat Pump
Resetting the heat pump should be a temporary fix. If you're resetting frequently, repairs may be needed.
Limits of Resetting
While resetting can resolve minor performance issues, it is not a long-term solution. Excessive resetting suggests problems needing diagnosis.
Common Heat Pump Repairs
Frequent resets may indicate these faults needing professional service:
- Refrigerant leaks
- Electrical components
- Drainage obstructions
- Dirty air filter
Assessing Repair Needs
Consider heat pump repairs if you have reset more than 2-3 times over a few months. Also if the reset button no longer works at all. Look for declining efficiency too.
Professional Diagnosis
HVAC technicians have tools to test heat pump operation after resets. They can pinpoint any underlying cause requiring repair.
Costs of Repairs
Heat pump repairs average $200-$800 depending on the make, problem severity, and parts needing replacement.
Preventing Future Reset Button Issues
Proper maintenance helps avoid reset button failures. Here are some tips for keeping your heat pump in good shape.
Maintain the Heat Pump
Follow the manufacturer's maintenance checklist. Replace filters, clear debris, check refrigerant charge and pressure. Inspect electrical components and tighten connections.
Operate Within Normal Conditions
Extreme weather or overworking the system strains it. Set your thermostat at moderate temperatures to prevent excessive runtimes.
Replace Old Units
Heat pumps over 10-15 years old are prone to reset issues. Consider upgrading your HVAC system for improved reliability.
Upgrade Thermostat
A smart or programmable thermostat offers better performance monitoring. Advanced controls can prevent conditions needing resets.
Avoid immediately calling an HVAC technician when your heat pump's reset button stops working. First, double check it's actually stuck and not a power supply issue. But if the button fails to pop up, resist forcing it as this could indicate dangerous electrical faults. Professional repair is the solution for any underlying problem causing repeated reset failures.
While occasional resets may get your system working again temporarily, excessive resets likely mean maintenance and repairs are needed for long-term operation. With proper care and fixes, your heat pump can go years without needing its reset button pushed.
