Got a stubborn keypad to work by hitting it with a hair dryer for two minutes
Had a customer in a cold basement with a panel that wouldn't arm, kept throwing a 'check keypad' error. The manual said to replace the whole unit, but I figured moisture might be the issue. I grabbed a hair dryer from my truck, warmed the keypad face gently, and it powered right up. Anyone else found a simple fix for a problem that the book says needs a full replacement?

Saw a forum post where someone fixed a glitchy touchscreen by just letting it sit in the sun for a bit.

Heat might dry out moisture shorting the screen, @kai942.

Wait, "dry out moisture shorting the screen" - so you're saying the heat itself could fix it by evaporating water? But wouldn't that also risk damaging other parts?
