The word「チン」is an onomatopoeia for the timer bell in earlier microwave models. Even though the timer bell has evolved into an electronic beeping sound, we still say チンする.

The First Japanese Microwave
Toshiba introduced the first domestically manufactured microwave in 1959. From there, Hitachi, Sharp, and Panasonic (all formerly under different names) came out with new microwaves one after the other.
The model that Panasonic introduced in 1963 propelled the popularization of microwaves, but microwaves were expensive at that time. The Panasonic model was 115万円 ($10,000). So it wasn’t until the late 1970s that general households were able to afford one at around $500.
