LANG ELECTRIC 36" CHEESEMELTER

http://www.jeansrestaurantsupply.com/about-us


A service call came in to our office from a customer stating that their electric cheesemelter was not heating at all. When our serviceman arrived he noticed one of the glass tube elements were broken and the coil on the inside of the glass tube was burnt in two. This particular machine has three elements, however, the way that its internally wired, when one element is burnt out none of them work. Therefore, no heat at all.

When he took off the brackets that hold the elements in place he noticed that one of the wires to an element was very frail and had burnt some of the insulation wrap from around it and left bare wire showing. These elements require special high temperature wire and ceramic wire nuts due to the extreme heat in the oven cavity.

With some new high temperature wire, ceramic wire nuts, and the new element he made his repair, reassembled the unit, and tested it.

NOTE: This particular piece of cooking equipment comes in either 208 volt or 240 volt ovens, therefore, you must purchase the correct elements that go to the specific oven. Also, the front and center elements are a different voltage rating than the rear element since the front and center ones are wired in series with one another.

CAUTION: Never use regular THHN or THW type electrical wire or plastic wire nuts in these units as they will melt and could cause an electrical short and/or fire.

VOLLRATH STRIP HEAT STRIP



A customer of ours called and said one of their heat strips in the pass-thru window was hot heating up. When our technician arrived and found that it was not heating he turned off the breaker so he could get into the control box area where he could check component parts and look for any possible wiring issues. Once he had the control panel cover off he immediately saw two burnt wires that the plastic wire nut had melted off of. The wires feed out of the power switch and lead to the element.

He then checked continuity and resistance on the power switch and the element to make sure they were still good and they were. The electrician had used thhn wire for the power and it was overheating and melting the plastic off the wire and melting the plastic wire nuts inside the control box. Plastic nuts cannot be used in the control box because of the extreme heat of the equipment.

The electrical supply to the heating equipment was in a metal flex conduit to the unit and about 3 feet away on the nearby wall the metal flex lead to a j-box. To alleviate the problem of wires and wire nuts overheating our technician ran high temperature wiring from the control box back to the j-box that was on the wall nearby. He also used high temperature ceramic wire nuts in the control panel near the heat.

He then put all the panels back on and tested the unit for proper operation. Problem solved!
