Pepco issued a fire hazard warning about some of their thermostats.
The warning only affects thermostats that are part of the Energy Wise Rewards program.
The batteries in the thermostat cause the problem. Those batteries are prone to leak, which can damage the circuit board, causing it to overheat.
Pepco is asking customers to remove these batteries. The good news is the thermostat will work properly without them.
The batteries only power the clock during a power outage.
