Furnace thermostat error


Many homeowners are surprised to find a green wire in the furnace control box, but the presence of the green wire is not unusual. The most common cause for a green wire coming from the furnace is when an installer crosses two wires and this error should be spotted by an inspection before being worked backward. It is unlikely that a retailer would sell these wires together because of how often they are crossed.

In newer heating or cooling systems, power is transmitted electrically through the thermostat to switch on the unit and heat or cool the motor coil inside. If a faulty wiring condition or worn attachment failed to maintain continuity between the wires, you may find bad ground and get a furnace thermostat error green wire notification.

The green wire that is no longer grounded acts as an emergency circuit breaker should the other wires fail. This wireless backup can keep you from spending up to $1000 on new motors if you remedy it quickly before it damages more of your system components.

If there are signs like no heat from the furnace, or if it becomes difficult to unlock the furnace door there is probably a problem with the thermostat.
