Heater Core Resistance
NOTE
Refer to the data sheet for wire-to-wire resistance of your vaporizer.
CAUTION
Turn off electrical power at the disconnect before performing this
procedure.
Remove the lid on the upper control box. Measure the resistance across each
pair of wires connected to OUTPUT (2) on the relays. An incorrect resistance
reading indicates a faulty heater element, a wiring problem, or an open fusible
link. If a fusible link is open, contact the factory. Do not attempt to repair it.
