rewired exactly as shown in the schematic.If there is still no
heat,call a servicing dealer/technician,the Ledco service
dept. or continue on to the advanced trouble shooting level.
As mentioned in the previous troubleshooting level,if you
have heat and no digital display read out,chances are
(provided all the respective wires and connectors check out
OK)the digital read out is faulty and should be replaced with
a new display from part # PRH130 heat control replacement
kit.Gently disconnect the plastic wire harness from its
receptacle on the back of the display by depressing the
small tab on the harness,then unscrew the three plastic
acorn nuts from the back of the display board to remove.Re-
install the new display in the exact reverse sequence.The
display should now be operational.If not,the problem lies in
either the ribbon cable or the heat control and you should
now consult a servicing dealer/tech,the Ledco service dept
or move on to the next,Advanced,level of troubleshooting,
diagnostics and repair.

Advanced.
With all of the previously mentioned
components checked and operational,if there is still no
heat,and specifically no heat with a digital display showing
three dashes(- - -),use a multimeter to check resistance on
the (disconnected)heat sensor wires.The sensor will have
an approximate resistance of 1.089 ohms at room
temperature.If the sensor has no resistance(or reads open
line or circuit)it is bad and should be replaced(part #
PRC212S) and rewired exactly as shown in schematic.To
remove the heat sensor from the heat shoe,first disconnect
the top heater wires and heat sensor wires from their
respective terminals.Loosen the small thumbscrews that
