ERR 2 with my MES 40

My MES 40 is throwing an ERR2 as soon as I turn it on and select "Set Temperature".. it beeps, error goes away and I continue to enter temp and time. Heat light then comes on but it does not heat.

Looking for any ideas prior to getting a new one (definitely not a Masterbuilt though).

Thank

Tony

I would call masterbuilt. They are pretty good about helping even if the warranty is up. You never know.

Wow. This exact thing happened to me yesterday with my MES40. The ERR2 started a couple of smokes ago on mine. I thought it was just the meat probe was spent. Then yesterday I turned the smoker on, hit set temp, got ERR2 like I had before. I set the temp to 275* and it heated up to @ 130* and then temp decreased back down to air temp. I saw the 'heating' light was on but the burner was cool...

I hope to break it down this weekend and see if it can be repaired. I hear that Masterbuilt wont sell the burner as a part now. Least that's what I read online...I also saw on you-tube the wires to the burner have a tendency to break down and lose contact...Hopefully its a simple fix.

Ill let you know what I see when I get some time to look it over...Bad timing for this for me....

If you google  "masterbuilt err2"  you will find a couple links to discussions.  With what I'm reading, it might be simply a loose or contaminated connection between the wires crimped to the heating element.  Then again, it might be something way more involved like with the controller.  I personally would look at the wire connection to element just to eliminate that possibility.

Maybe someone with hands on experience to this issue will chime in.

Ok, Got a few mins to take a look, and sure enough it was one of the connectors to the heating element had basically disintegrated.

Looking at the back panel of your smoker it is the small cover at the bottom. 6 screws and a thin rubber gasket that peeled off. There are 2 well insulated wire connections. Both look a little charred and compromised. One of mine was disintegrated where it was just touching the heating element connection. I touched it and pieces just crumbled away. I picked the rest of the rust and chunks off the wire and used a small wire brush to clean off the paddle to the heating element.

Gotta run to the h-ware store for a new paddle connector to crimp to the wire. I also plan to get some shrink-tube to slip over the connection and an inch or so up the wire for good air and moisture free connection.

I thought about tearing apart the other connection and rebuilding it but I think I will wait..I dunno...don't wanna push my luck...

Happy to hear any other electrical recommendations for redoing this connection. Will the shrink wrap be enough insulation?

Ill post back after I get the parts and finish the fix...

Strip rubber off of back plate and stretch over screw heads so I can rip it off and reinstall quickly to inspect when unplugged before my next smoke so no future dilemmas.  Once bitten twice shy so to speak.  I make these and mail them to SMF members with this exact problem.  You can wire nut the pigtail setup in the pic above or solder and shrink tube like I did to the MB leads.  PM me if you want a couple. No problem I like doing this kinda thing.

Thanks for all the replies, AndyPanda when I looked mine was exactly as you described. Cleaned the paddle, crimped a new connector on and all is working. It still throws a Err2 upon power on but otherwise heats up, shuts on off at temperature and I am good to go. 10 minutes fix with a $0.10 part.

Annoys me that I did not just dive in as I am a tinkerer but have had so much trouble with this smoker and I was entertaining that day and all my food plans were in the smoker that day.

I may have one more crimp and clean in the unit before the heating element falls apart.

Thanks again

jumping around trying to get some one to help. Ordered a new control board for my older Gen 2. Now the older ones have 3 plugs a 5 wire a 3 wire and a two wire. my new control board has a 5 wire and two 2 wire plugs which I'm told all the newer ones have.

 The part supplier says they distribute the parts for MB and they told them to print on the invoice to call tech support to learn how to hook the new 2 wire to the old 3 wire.

 I did and the tech had no idea what I was talking about. He told me I would have to buy a new smoker because the parts for the old GEN 2 are no longer available.

 But apparently there is a fix. has anyone had this problem and could tell me how to connect the wires?

 Oh well, what do you expect from a smoker made in China

bird731713 - IF you decide to buy a new smoker, be sure to look over the line from Smokin-it, in addition to looking at the MES.  Smokin-it is more expensive but rock solid and dependable.  I am very impressed with the quality and performance.

Hi All. Just getting a chance to report back. The fix worked just like described above however I also still get an ERR2 when I turn on the unit.

The 2nd connection cracked apart while I was fixing the first so it was rebuilt as well. I crimped on a paddle connector tested the fit, slipped on some shrink-wrap to cover the wire connection and to extend down past the end of the paddle to cover the heating element contacts heated shrink-wrap up with a mini-torch and insulated and weatherproofed the connections.

Overall easy fix and now the unit is much-much faster to come to temp and I get good smoke from the smoketray.

Let the beast eat!!!
