I bought a Toper 10k roaster from a lady whose husband passed away. She didn't know anything about the roaster. I'm getting used to it but I'm having an issue where the temp controller, Emko ESM-4430 will inadvertently go out during the roast killing the flame and for no apparent reason it will come back on and everything will be fine until it does it again at any random time. Has anyone experienced this or have any ideas? Also looking for contact info for Toper, I sent a message to the e-mail address I have but never heard back.
