Is my thermostat on the same breaker as the oven?
Are you planning to replace your thermostat but can't find its circuit breaker?
The thermostat is on the same switch as the oven if you are using a centralized HVAC system. In a centralized system, all components are connected to one circuit breaker. Otherwise, the thermostat breaker is the same as any component from which it receives power. This could be a furnace, an air conditioner, or any other component of an HVAC system.
Keep reading to find out which circuit breaker your thermostat is connected to.
Ovens with one circuit breaker
Most homes have a centralized oven that controls all temperature-related appliances.
This oven is part of a central HVAC system. The central HVAC uses only one circuit breaker for all of its components. The temperature in the house is controlled by the oven thermostat. Turning off the circuit breaker will turn off the entire HVAC system.
The thermostat acts as a control switch for the HVAC system. It turns on the power to the air conditioner heater and sets it to a certain temperature.
All components of centralized HVAC systems are interconnected.
The main disadvantage of this system is the use of a single switch. If one component trips the switch, the others will automatically shut down. For example, the oven and thermostat will turn off if the air conditioner fails. On the other hand, it serves as a preventive measure to prevent more serious complications such as blown fuse by the circuit breaker.
Ovens with multiple circuit breakers
Some ovens must use dedicated circuit breakers for each of their components.
An HVAC system can use multiple circuit breakers to control each system. This is usually done for energy intensive HVAC systems as it is safer to have each component on its own breaker.
A powerful thermostat is directly extracted from a single component. It controls the heating and cooling of any component it is connected to. The disadvantage of multiple circuit breakers is that you will need to determine which component is providing power to the thermostat.
It is easy to trace the thermostat circuit breaker if you are familiar with the wiring of the HVAC system circuit. Otherwise, you will need to check the electrical panel of each circuit breaker. It can be connected to an air conditioner, oven or other HVAC components. Observe which of them will respond to the power of the thermostat. In most cases, the thermostat is connected to the heating and cooling components.
Separating the thermostat from the component circuit breaker is a difficult task.
You will need to reconnect the thermostat to another component, such as an air conditioner, in order to turn it on. This is easier said than done. In addition to fixing the A/C wiring thermostat, you will need to rewire all components to make sure they are fully functional after the transfer. This is a complicated procedure, especially if you are not familiar with circuitry and other electrical systems.
Replacing the thermostat
Energy Star certified thermostats are becoming the preferred model among homeowners.
To replace the power thermostat must be turned off. First, determine if your oven is connected to a centralized HVAC system. If so, turn off the system breaker to turn off the thermostat. Otherwise, track where the thermostat draws electricity to turn off the power.
Replace the thermostat when it is off. Reactivate it by flipping the appropriate switch in the switch box.
