This fridge is 5/6 yrs. old and has been though several power surges.

If several transients that exceeded 1000 volts existed, then how many other appliances were damaged?

A blackout (outage) is not a surge. However advertising promotes that myth to sell plug-in protectors. If a surge existed, then other surge destroyed appliances are listed. What protected the dishwasher, GFCIs, clocks, and so many less robust appliances?

Your symptoms are more consistent with a more common reason for failure - manufacturing defect. To say more means a failed motherboard part must be defined. A dead body is always best evidence.

Meanwhile, if a properly earthed 'whole house' protector does not exist, then you have all but invited surges to come inside. To threaten central air, dimmer switches, microwave, GFCIs, garage door opener, furnace, LED & CFL bulbs, and smoke detectors.

Only a manufacturer can prevent manufacturing defects. Only a 'whole house' solution (properly earthed) is effective protection from something that occurs maybe once every seven years (surge). To even make surge damage easier, then use an adjacent power strip protector.
