What must be done before servicing a propane appliance?

Before servicing a propane appliance, it is essential to shut off the propane supply and disconnect power if applicable. This step is crucial for safety reasons. Propane is a flammable gas, and working on an appliance while it is still connected to the gas supply poses a significant risk of leaks, fires, or explosions. Additionally, disconnecting power ensures that the appliance will not accidentally turn on during service, further mitigating hazards.

Taking this precautionary measure helps create a safe working environment, allowing technicians to inspect, repair, or maintain the appliance without the risk of an active gas flow or electrical hazards. Following this procedure is a standard practice in both residential and commercial settings where propane appliances are used.
