To perform a basic maintenance check on your Lennox 12CHP unit, start by turning off the power. Clean or replace the air filter, inspect the outdoor unit for debris, and clean the coils. Check for any unusual noises or vibrations and ensure all panels are securely attached.
If your Lennox 12CHP isn't heating properly, first check the thermostat settings and ensure it's set to the correct mode. Inspect the air filter for dirt and replace if necessary. Make sure the outdoor unit is clear of debris. If the issue persists, contact a professional technician.
If your Lennox 12CHP won't turn on, check the circuit breaker to ensure it hasn't tripped. Verify that the thermostat is set correctly and the batteries are functional. Inspect the power switch near the unit. If these steps don't resolve the issue, consult a professional technician.
Regular maintenance of the Lennox 12CHP ensures efficient operation, reduces the risk of breakdowns, extends the lifespan of the unit, and maintains optimal air quality. It also helps in identifying potential issues early, preventing costly repairs.
