You run one load and it comes out flawless. Then, for no apparent reason, the next load is a mess—internal stress, weird optical distortions, the works. Most engineers start by obsessing over the timer or checking the furnace insulation. But usually, the real problem is hiding in plain sight: your infrared (IR) lamps aren&rsquo;t actually putting out the same amount of heat.</p>
