Questions and answers
No digital display on front of venstar t1800
The Venstar T1800 thermostat requires 24V power from the HVAC system. If the digital display is blank, it may indicate a loss of power. Possible causes include a blown 3 or 5 amp fuse on the control board, a tripped breaker, or an improperly secured door panel on the indoor unit, which could prevent the door switch from engaging.
