    Make sure power is on to the unit.

    If the thermostat is battery operated check the batterys.

    It is possible there is a fuse in your unit so you can check for that. NOTE before you go playing in the electric for a fuse I suggest you turn off the power so you do not get hurt.

    Merry Christmas.

    You can try looking for a kicked breaker or blown fuse in circuit board,, but possible a bad transformer
