I think my oven is not maintaining the correct temperature anymore because the pumpkin custards I bake frequently are taking much longer to cook than they previously did.
I have a mercury-type oven thermometer and a DMM with a temperature probe. What is the best place for me to position the thermometer? What is the best place for me to position the probe from the DMM? Should I keep the probe from touching the wire racks?
How long should I wait after the oven indicates that is up to temperature before I look at the thermometer? Is there some other way I can check the thermostat? The oven is a Frigidaire model FEB24S5ASB. It was made in September 2003. It has a digital control panel.
Thank you in advance for all replies.
