causing these noises?
Questions and answers
Q: Why wonʼt my oven turn
on?
A: When the oven does not turn on, check the following:
1. Is the oven plugged in securely? Remove the plug from
the outlet, wait 10 seconds and reinsert.
2. Check the circuit breaker and the fuse. Reset the circuit
breaker or replace the fuse if it is tripped or blown.
3. If the circuit breaker or fuse is all right, plug another
appliance into the outlet. If the other appliance works,
there probably is a problem with the oven. If the other
appliance does not work, there probably is a problem
with the outlet.
If it seems that there is a problem with the oven, contact
an authorized Service Center.
A: Some radio and TV interference might occur when you cook
with the microwave oven. This interference is similar to the
interference caused by small appliances such as mixers,
vacuums, blow dryers, etc. It does not indicate a problem
with your oven.
A: The oven is designed not to accept an incorrect program.
For example, the oven will not accept a fourth stage.
A: The heat given off from the cooking food warms the air in
the oven cavity. This warmed air is carried out of the oven
by the air flow pattern in the oven. There are no
microwaves in the air. The oven vents should never be
blocked during cooking.
A: Only when you are using GRILL cooking mode. The metal
in some thermometers may cause arcing in your oven and
should not be used on MICROWAVE and COMBINATION
cooking modes.
A: The noises occur as the oven automatically switches from
MICROWAVE power to GRILL to create the combination
setting. This is normal.
A: This display indicates a problem with the microwave
generation system. Please contact an authorised Service
Centre.
