Microwave Sparking Inside in Fullerton

Microwaves in Fullerton homes face unique challenges that contribute to interior sparking issues. In the older downtown neighborhoods near Cal State Fullerton, we regularly service 15-20 year old units in rental properties where college students have unknowingly damaged waveguide covers by microwaving metal containers or aluminum foil. These older microwaves, particularly the Kenmore and GE models common in the Craftsman bungalows and post-war housing along Commonwealth Avenue, develop deteriorated interior paint over time, creating hot spots that lead to arcing.

The housing variety from downtown to Sunny Hills means we see sparking issues across all price ranges. In the mid-century ranches throughout central Fullerton, Samsung and LG microwaves often develop worn turntable couplings that create metal-on-metal contact points. Meanwhile, the premium Thermador and Viking units in the hillside custom homes sometimes experience waveguide cover failures due to the combination of heavy use and Fullerton's inland heat affecting the plastic components over multiple summers.
