Thermostat causes short cycling: system turns on and off frequently in short bursts

Safety first: Only low-voltage configuration changes are needed.

• Step 1 – Check cycle settings: In the thermostat installer or advanced menu, adjust the cycle rate or temperature differential to a lower cycle rate (fewer cycles per hour) and a slightly wider differential.
• Step 2 – Verify location: Ensure the thermostat is not directly in the path of supply air or near heat sources that cause rapid temperature changes.
• Step 3 – Observe operation: After adjustments, monitor the system for several hours to see if cycle length increases.
• Step 4 – Consult professional: If short cycling persists, the Amana equipment may be oversized or have other issues (like limit trips) that require professional diagnosis.

When to call a professional: Persistent short cycling can damage equipment; have an HVAC technician evaluate the system.
