Fan (#) Motor Overload
This indicates that one of the fan motor thermal overloads has opened. This overload is
located in the fan/heater box associated with which fan motor overload has opened. The
message will display in which fan the overload occurred.
Example: Fan #1 Motor
Overload on up to Fan #6 Motor Overload depending on the size of the dryer.
The overload must be manually reset by pressing the red reset button on the overload. After
pressing the reset you should have a LED on beside the Fan Motor Overload terminal J4-10.
This is on the fan/heater interface board where the row of LED’s are located. If you are
using a voltmeter you should have 12 volts DC on the following: (Remember when checking
for 12 volts DC always put one probe of meter on the DC negative.)
( J5-03 ) DC Negative
( J4-01 ) 12 Volt DC output LED should be on.
( J4-10 ) 12 Volt DC when closed (Fan Motor Overload) LED should be on.
Housing (#) Temp Hi Limit
This occurs when there is an overheat in the fan housing of 200 F degrees. The fixed
temperature thermo disc has opened. It is located directly on top of the individual fan hous-
ing and will have to be manually reset. The high limit is wired directly to the fan/heater
interface board where the high limit occurred.
Example: Housing #1 Hi Limit on up to
Housing #6 Hi Limit depending on the size of the dryer. After pressing the reset for
housing hi limit you should have a LED on beside the Housing Hi Limit terminal J4-09.
This is on the fan/heater interface board where the row of LED’s are located. If you are
using a voltmeter you should have 12 volts DC on the following: (Remember when checking
for 12 volts DC always put one probe of meter on the DC negative.)
( J5-03 ) DC Negative
( J4-01 ) 12 Volt DC output LED should be on.
( J4-09 ) 12 Volt DC when closed (Housing Hi Limit) LED should be on.
Burner (#) Gas Pressure Hi Limit
This occurs when gas pressure rises above or falls below preset limits on the Mercoid gas
pressure switch. This Mercoid switch is required only in Canada. The message will show
on which burner the error occurred.
Example: Burner #1 Gas Pressure Limit on up to
Burner #6 Gas Pressure Limit depending on the size of the dryer. The Gas Pressure
Limit is wired directly to the fan/heater interface board where the shutdown occurred. If both
limits are satisfied there should be a LED on beside the Gas Pressure terminal (J4-05).
This is on the fan/heater interface board where the row of LED’s are located. If you are
using a voltmeter you should have 12 volts DC on the following: (Remember when checking
for 12 volts DC always put one probe of meter on the DC negative.)
( J5-03 ) DC Negative
( J4-01 ) 12 Volt DC output LED should be on.
( J4-05 ) 12 Volt DC when closed (Gas Pressure) LED should be on.
