If your Honeywell thermostat has gone blank, it could be due to various reasons. One common cause is a power issue. Check if the thermostat is receiving power by ensuring it is properly connected to the electrical source. Another possible reason is a blown fuse or tripped circuit breaker. Inspect the fuse box or circuit breaker panel and reset or replace any damaged fuses or tripped breakers. Additionally, a malfunctioning thermostat or a software glitch can also cause the screen to go blank. In such cases, it is advisable to consult a professional HVAC technician for thermostat repair or replacement.
