If your heating or cooling system isn't responding, try the following: * Set the system to Heat and ensure the temperature is set higher than the inside temperature. * Set the system to Cool and ensure the temperature is set lower than the inside temperature. * Check the circuit breaker and reset it if necessary. * Make sure the power switch at the heating & cooling system is on. * Ensure the furnace door is closed securely. * Wait 5 minutes for the system to respond.
