TROUBLESHOOTING

PROBLEM

Product is toasted

too dark or too

light.

PROBABLE CAUSE

Toaster was not adequately

preheated.

Preset toasting time is incor-

rect.

Using refrigerated or frozen

bakery products.

CORRECTIVE ACTION

Allow toaster to preheat until 

 (ready) ap-

pears in the display.  This should occur about 15

minutes after electrical power is restored to the

toaster.

Enter Programming Mode to increase or decrease

the toasting time as necessary.  Refer to the Pro-

gramming section of this Manual.

Bakery products must be at room temperature BE-

FORE toasting for consistent results.  Allow a 2-

day-old rotation when using fresh bakery products.

Bakery product is

jammed in toaster.

Loading is excessive.

OR

Product is loaded incorrectly.

OR

Carbonized deposits on

lower deck are sticking to the

bakery product.

Switch the 

 switch to the OFF (“O”) position.  Wait

for the fan to stop operating.  Then, switch the circuit

breaker/fused disconnect to the OFF (“O”) position

and allow the toaster to cool.
Next, carefully clear the jam using a long object as

a probe.  The probe should preferably be made of

wood, which is less likely to damage the heating

elements.

WARNING

NEVER USE A PLASTIC OR METAL

OBJECT AS A PROBE TO CLEAR A JAM.

WARNING

DO NOT INSERT THE HANDS INTO THE

TOASTING CHAMBER TO CLEAR A JAM.  IF THE

UNIT HAS NOT COMPLETELY COOLED, SEVERE

INJURY MAY RESULT.

After clearing a jam, thoroughly clean the peel and

the lower deck before resuming operation.  Refer to

Cleaning the Peel and Lower Deck in this Manual.

erative.

Switch the 

 switch to the OFF (“O”) position.  Wait

for the fan to stop operating.  Then, switch the circuit

breaker/fused disconnect to the OFF (“O”) position

and allow the toaster to cool.
Thoroughly clean the fan before resuming operation.

Refer to Cleaning the Toaster in this Manual.

If the problem persists, or is not described above, contact your Authorized Service Agent.
