About the Marley 5823-0002-000

The 5823-0002-000 is a control terminal block from Marley Engineered Products. It is the connection point where the control wiring inside the heater lands, giving those wires one secure, orderly place to connect.

It is used in Marley electric unit heaters. Signs that a terminal block needs replacing include cracked or heat-discolored housing, stripped screw terminals, or loose connections that cause the heater's controls to act intermittently.

Compare your heater's model number with the compatible-models list on this page before ordering.

Installation Tips

Shut off power to the unit heater at the breaker and confirm it is dead with a tester. Label each wire before taking it off the old block, mount the new block in the same spot, and tighten each wire firmly under its matching terminal before restoring power.
