What do I do if the kiln heats too fast?

The Knowledgebase is organized into a series of questions and answers having to do mostly with technical troubleshooting and understanding of kilns.
Although we write this for our own kilns many of these articles apply to other makes - although L&L takes no responsibility for that.
Many Knowledgebase articles have Actions, PDFs and Videos associated with them.
Actions are specific actions for you to take during the troubleshooting or repair process.
Each Action may also have Videos and PDFs associated with it and, in addition, specific Cautions.

Applies to Current Kilns Series:

Check your voltage. Some people may have high voltage like 245 volts where you should nominally have 240 volts.
Make sure you don't have a 208 volt kiln hooked up to a 240 volt circuit. This is dangerous because the kiln will draw more amps than it is rated for which will overload the power wires and other components and could cause a fire.

Check element ohms and compare with factory values. (See CHECKING ELEMENT OHMS).

Check Your Voltage

Check your voltage at the receptacle or at your fused disconnect box. Check voltage at your panel and where the kiln is connected. Check the voltage when the kiln is firing and when it is not firing.
Make sure no other large electrical appliances such as a clothes dryer or electric oven are on when you are operating your kiln.
Find out from your local utility company when the end of the peak period of electrical use is.
Check to see what the wire size of your circuit is. If it is very far (more than 50 feet) from your main circuit box then the wire size might need to be higher.

Checking Elements

With all power OFF, pace the test leads of the multimeter of the each of two of the terminals marked 1 and 2, 3 and 4, or 5 and 6 on the element terminal strip. Compare the reading you get to the reading you get from the other element terminals. Also check against the wiring diagram for the ohms listing.

With all power OFF, pace the test leads of the multimeter of the two flat prongs of each section's jumper cord, one on each prong, OR on both connecting wires, at the connection points with the elements. Compare the reading you get to the reading you get from the other jumper cords or connecting wires. Also check against the wiring diagram for the ohms.
