Probable Cause

Power Cord is not plugged in.

Circuit Breaker is tripped off in the

site's breaker box

Transformer has taken a electrical

surge and is damaged

Check voltage on the secondary side

of the Transformer. If you read

12VDC then you are receiving voltage

to the Controller.

Controller is damaged

Possibly control needs to reset

The relay driver on the digital control

may be blown.

Sensor lost it's continuity as shown

on a muti-meter.

The tactile buttons under the overlay

may be not close enough to activate.

Same goes if the buttons are already

pressed by overlay without

depressing button.

The Relay on the switched side is not

opening to regulate temperture.
