Cudos to ThermoWorks
I emailed them about an error display on my RT301WA Digital Thermometer.
They responded quickly and advised me to remove the battery for a while, then reinstall it to see if that would solve the problem. I tried that and still had an error message. I emailed them back, mentioning that I no longer had the receipt. I received an email stating that they looked up my order and were shipping me a new unit. They are a class act.
