contactor BUZZzz

[palmbeach]

I have just fired up my oven for the first time today and every thing ran fine, until I turned the thermostat off then back on. now the contactor is making a buzzing noise (a little to loud for my liking). I am using a 50 amp 3 pole Allen Bradley contactor, four elements, with 8-gauge wire. has any one had this problem??

check and make sure that the contactor has the prper voltage for the coil. i had a freind that it needed 240V for the contactor and he tried to trigger it from the timer with 120V, hense the buzz

just a thought

just doubled checked the specs on the contactor and the coil is listed for 120v

Ok...then the relay needs to see 120V for the contactor to stay engaged...simple fix, and can even come off one of the 220V source lugs and run that through the timer....I did that for my buddy and it worked fine after that...keep in mind we had a ground lug in the box...went like this....from ground lug to one side of the contactor coil-120V hot from source lug to timer-out of timer to other side of the coil on the contactor...hope that helps
