Possible Causes

Cycle rate set too high in Wyze settings, Oversized HVAC system, Furnace high-limit or low-pressure switches opening, Clogged air filter or restricted airflow

How to Fix / Troubleshooting

Safety first: Turn off furnace power at the breaker before inspecting internal components.

  • Adjust cycle settings: In the Wyze app, reduce the maximum cycles per hour for heating and cooling if adjustable.
  • Replace air filter: Install a new, properly sized air filter to ensure adequate airflow.
  • Inspect vents: Make sure supply and return vents are open and unobstructed.
  • Have equipment inspected: If short cycling continues, an HVAC technician should check for high-limit trips, pressure switch issues, or system oversizing.
