Confirm Pow Er Supply - Lennox Merit MPE36 Service Manual

• When the electric fireplace
is initially connected to a
power supply:
– By plugging in the power
cord to a receptacle
– By turning on the circuit
breaker (hard wired
connection at the junction
box)
• The control board will emit two
loud "beeps" to confirm
"power up".
• If you do not hear these
'beeps":
– Confirm that the circuit
breaker is "on"
– Confirm power to the
receptacle.
– Is an external switch
controlling the power to the
fireplace? If so it must be on.
• If power is available to the
fireplace and the two "beeps"
are not sounded at"power up",
look for:
– Transformer failure (page 9)
– Control board failure
