Troubleshooting Guide
1. Is the oven plugged in and the
ON/OFF switch in the ON position?
2. Is the display blank?
If YES is the electrical supply denitely turned on?
Have you tried the plug in another socket (if available)?
3. Are there any Error Codes or Messages on the screen?
4. Is the oven preheating to the Correct Temperature
(250°C), when the oven is turned on? The display
will show the CATEGORIES screen when the correct
temperature is reached.
(Note: This can take up to 30 minutes.)
5. When you start to cook a product does the oven display
Error Codes or Warning Messages?
(Normally the display will show a timer counting down to
zero)
6. When the cooking cycle is complete
does the warning bell sound?

COOKING ISSUES:
If food products are not cooking correctly then
please use the following questions to try to
pinpoint the problem.
Merrychef service technicians can only change
oven settings by the use of the correct Menukey.
Please note that not all questions may be
applicable to the issue you are experiencing:
1. Was this problem present at the time you
received your Merrychef oven?
2. Did the problem correspond with a new
shipment of product(s)?
(For example, perhaps the size of the
product changed since the menu has been
developed).
3. Is this an intermittent problem or always
present?
4. Does the problem happen regardless of the
type of food you are cooking?
(as opposed to happening only when a
specic type of food is cooked)?
6. Are you using the correct programme?
(Review the Operations Guide if you are
unsure).
7. Are all employees following correct cooking
procedures?
8. Are there any alarm codes or warning
messages on the screen?
9. Is the food item being cooked at the correct
starting temperature?
10. Is the food item being removed from the oven
immediately when the cooking is complete?
