About the Marley 4520-5015-001

The 4520-5015-001 is a high limit control for select Marley, Qmark and Berko electric heaters. It is marked with a white identification dot and is rated to cut out at 170°F.

The same heaters also use a separate one-shot fuse, part 4520-2041-000, which is sold separately. Confirm your heater is in the compatible-models list on this page before ordering. White refers to the identification dot, not the color of the part.

Installation Tips

Disconnect power at the breaker and allow the heater to cool before replacing the limit.
