Why has my thermostat screen gone blank?

Generally, one of two circumstances has occurred. It could be that your drain line has become clogged and the “Float Switch” has automatically shut the system down. This is done to prevent any water damage to your home from an overflowing drain. A fuse within your air handler that has failed and shut the system down could also cause this problem. Please call for service and we will be happy to send out one of our trained technicians.
