Service Tips

NOTICE:  Any work performed on EDGE appliances that are under factory warranty must abide by the MF&B Warranty Policy.  Any work performed without prior authorization may not be reimbursed by MF&B.  All EDGE appliance owners and services companies/persons should contact MF&B prior to any service call and obtain a Service Authorization number.  Modifications to the EDGE appliance and the use of non OEM repair parts, without prior consent from MF&B, will void the balance of the factory warranty period.  Authorized service persons must contact MF&B during the initial visit to expedite the repair process.  Please familiarize yourself with the Warranty Policy, Installation & Operation Manual and the Service Manual before performing any service on the EDGE oven.

Oven stops heating, gets quiet...

The most common problems are prevented by maintenance cleanings.  The most often area that is overlooked is the Circulation Fan Motor.  This motor is exposed on the back of the oven.  If the motor ventilation grill is not regularly cleaned, the heat of the oven WILL cause the motor to enter a state of thermal protection.  This problem often shows itself when you least want it to occur, during peak hours.  As the oven demand increases, so do the BTU/Hr, causing more heat to travel down the motor shaft and to be delivered directly to the motor.  In normal situations, the motors internal fan cools this heat and the motor can function normally.  When clogged, the motor will overheat, shutting the entire combustion system down.  Please keep your oven operating reliably and clean the motor ventilation grill on a monthly basis.

Temperature drops suddenly

The EDGE oven is highly efficient and burns extremely clean, but this alone with not eliminate nasty Hydrocarbons and other contaminants from depositing on the Electrodes.  The process of baking can create grease laden vapor, ash and of course Hydrocarbons.  Over time, these byproducts can buildup and effect the combustion system electrodes.  Depending on the products you are baking, the amount of these byproducts will vary.  Often the first symptom of dirty electrodes may start as such: The oven is steady at temperature and then falls quickly, only to recover and begin climbing again.  This may progress until the oven eventually enters a safety lock-out mode and the temperature just continues to fall.  The solution to this problem is to have the oven burner cleaned.  The electrodes are simply metal rods and can cleaned many time during the life of the part; however, a trained service technician is recommended for this task.  The process is similar to furnace burner cleaning and you may already have a guy or gal for that.  Please visit our Instructional Videos page for more information.

Appliance Clearance

The EDGE oven requires 6 inches of clearance from the sides and from the back (see Installation & Operation Instructions).  The primary reason for this is to allow the appliance to ventilate and cool.  The control cabinet of the EDGE oven contains a number of electronic devices.  Care must be used when positioning equipment around as to not block the oven fans and to not encroach on the minimum clearance.  Cooking equipment within proximity of the oven control cabinet can radiate heat and cause intermittent and sudden component failures.  See section 1.4 of the warranty policy for details.
