Possible Causes
Indoor unit calling for heat while outdoor is in cool-only mode, Incorrect dip switch or configuration settings on control board, Incompatible thermostat or wall control, Faulty indoor control board logic
How to Fix / Troubleshooting
Safety first: Turn off power to the system before accessing control boards.
- Step 1 – Thermostat check: Verify the thermostat is correctly set to COOL mode and not to HEAT or AUTO with conflicting schedules.
- Step 2 – Confirm system type: Ensure the thermostat is configured for a conventional split A/C system (not heat pump) if your Keeprite unit is cool-only.
- Step 3 – Board configuration: On the indoor control board, check dip switches or setup jumpers against the Keeprite installation manual. Correct any mismatched settings (e.g., heat pump vs. straight cool).
- Step 4 – Reset configuration: Some Keeprite controls allow a factory reset via button sequence. Perform a reset if documented in your manual, then reconfigure properly.
- Step 5 – Professional diagnosis: If E7 remains after confirming thermostat and board settings, the indoor control board may be defective and should be replaced by a professional.
