[AwwNuts]

In need of your help once again. This is the second unit that failed on me and luckily I was home to catch this. After noticing what seemed to smell like burning plastic, I immediately checked around the aquarium and discovered the Tunze 3152 box heating up, shell melting and leaving a strong order of melting plastic. Looks like i caught the unit failing right on time. I immediately disconnected the unit and moved it to a safe area just in case it was going to continue to melt or catch fire. This unit was a replacement that was sent to me through the assistance of this forum back in 2015-2016.

Requesting help once again. I've attached pictures for your review.
