SPECIFIC ERRORS AND ISSUES
The technically advanced diagnostic capabilities of the
electronic controls utilized on the 1200 and 2200 series
units allows for easy and thorough troubleshooting.
Navigation of the control is the key and is explained in the
CONTROL OPERATION section of the manual, along with
control button layout, control function descriptions, a
service mode menu and service menu selection
explanations.
Verification of temperature and thermistor performance
can be identified by directly viewing thermistor readings in
the service mode.
Component failure issues can be identified through service
mode menu #19, “Component Testing.” Individual
components can be switched on and off to check for both
proper function of a specific component and also delivery
of supply voltage to the components through the relays
and DC outputs located on the relay/power board.
