masterbuild not heating

[Tee]

Masterbuilt electric not heating up. Digital controller, heating element replaced. Wire connections all good, the only thing left is temp sensor and is not a replaceable part. Very disappointed only one year old and not used that often.

Now I did a face plant into my palm the other day. My MES 30 wasn't heating, seemed like it started but came back 15 minutes later and it's 92 degrees. I totally forgot you have to set the timer for it to heat. No time set, no heat. Just a thought.....since it just happened to me.

Hi there and welcome!
tktplz brings up a good point so be sure to check that.
Also avoid using an extension chord unless you are using a 10-12 AWG chord under 50 feet.

Did you check the connectors to the safety rollout limit switch?
This is the other major failure point on the MES.
This is what it looks like with the panel removed... if you have an access panel for it. Gen 1 models do not have an access panel to it and you must pull the back off the MES to get to it.

Hi and welcome Tee. You did not indicate the model you have. I have a gen 1 30" (20070910) The temperature safety switch goes by a few different names. Roll out switch,snap switch are 2. My switch is accessible. I had to drill out the rivets on the back panel with a 1/8" bit. There are a bunch but after you get started it does not take that long. Instead of re riveting I replaced them with SS #8 1/2" truss head screws the truss head screw has a larger head than a pan head screw. The temp switch prevents a runaway situation by cutting off the power to the element. That switch may very well be on the left side of the back just over 1/2 way up. It is visible and is about the size of a nickle You need a volt ohm meter to check it. See if it has continuity through the switch. The switch is normally closed. If you don't have continuity the switch is open and bad. It is not hard to replace and available from Amazon for less than 3 dollars. Jted
