Hi. New to the forum. I was given a Masterbuilt 30" Electric Smoker. It was free but not working. The person replaced the top controller and the heating element. I have one exactly like it so I can use it for parts if nothing else. I like to explore and find out what's wrong with stuff so I decided to try fix it. I started off checking some basic stuff, the element (800W ohms out to about 19... I think that's close), the controller is new and seems to be fine.....at least all the settings work and it lights up. I did notice that when it sends power to start the heating process, I don't hear any noise like I do with my current one. I then removed the back panel to check the thermostat and thermal fuse. I really didn't have a way to check the thermostat so I heated it with a match it the temperature went up on the display almost immediately. I assumed it was fine. I also had no way of checking the thermal fuse so I bypassed it and tried to start the smoker. Nothing happened. I assumed it was fine as well. I then decided to check the board at the bottom of the smoker and found that one of the leads (the common) was melted on the black relay. I did check the voltage going to the relay and it was 120V. I also checked the voltage going to the coil and it was 4V. Is it safe to assume that the relay is bad and if so, how can I test it to be sure? It is a two prong, normally open relay. Thanks for any advice.
