Tankless Water Heaters
The notice says to stop using it — see below for what to do.
What’s wrong
Components inside the water heater may shift during transit, causing an air filter door switch to operate improperly. If the switch fails and the air filter door is out of place, the water heater could continue to operate and dust and lint could build up, posing a carbon monoxide poisoning hazard.
The Recall Registry rates this serious — The agency says to stop using it immediately.
