Masterbuilt Grilling - Recent Questions, Troubleshooting & Support


The unit will not turn on if the internal temp sensor is below 40 degrees. Warm it with a hot rag or hair dryer, or bring the unit inside to warm up and it will turn on. Once the unit turns on for a minute or so, it will work fine outside.

This isn't the ideal solution, but it will work. I don't know why they don't want the smoker to turn on when it is cold out (unless they are worried that the quick change in temp will damage the heating coil).

READ FIRST! Before trying any of the lengthy suggestions regarding repairs on Masterbuilt electric smokers, consider this. It APPEARS (based on testing, not reverse engineering) that Masterbuilt designed the controller on my unit (140S) to error out below a certain minimum temperature. If you are like me and have your smoker outside (as you should), but in sub freezing temperatures, you too may get this error. Just shoot the short temperature probe (on the back wall of the cabinet) with a hair dryer for a minute or two. Then plug back in for no error (assuming you do not have an actual wiring or probe failure). Just make sure to immediately start it heating before it drops too low again... If this was by design, shame on Masterbuilt! If this was by error, shame on their engineers! If this behaviour is due to an intermittent problem with my unit, shame on me for not fully testing all possibilities once I found an easy fix...

Here's is a link to the part you need. http://www.appliancefactoryparts.com/search/partinfo.php?partsID=491507&modelsID=135884&typeName=gas%20grill

The problem you're having is quite common with Masterbuilt Electric Smokers.

Hope this helped you & thanks for choosing FixYa.

You are not the first Masterbuilt Electric Smoker owner to have this problem. The Model 20070106 has been plagued with electrical problems from day one. Maybe, that's why it only has a 90 day warranty?

As far as parts are concerned, you can call Masterbuilt (800-489-1581), first to see if they can help you. More than likely, you will need to replace the electronic control panel on the top of the smoker and maybe the electric element, too.

Another place to try is www.factoryapplianceparts.com.

Masterbuilt Digital Smoker no longer heats up and digital display has stopped working completely. The unit acts like there is no power to it and is completely dead. By replacing the digital component will this solve my problem

gas pressure too low check pressure adjust to correct if ok check for blocked burner tube

Unplug and let sit, maybe it has a circuit breaker inside which resets itself. If that does not work I would suspect the thermostat.

Try this site for a manual for your BBQ grill. If they do not have it, check with google.

I am not clear how an electric smoker works but I am guessing there are two basic problems - one of design and the other of material specification. I have dismantled many electric heaters of various sorts, lots made redundant because they were old-fashioned and expensive to run. Some of them were in excellent condition even though they were perhaps up to half a century old. The remarkable thing about the design of these was how substantially over engineered they were. This was partly due to the fact when they were built a significant number of homes and offices were using direct current mains electricity, consequently the switches needed powerful springs to ensure a rapid connection and disconnection and the large contact area had a wiping action with a classic knife-switch design. Poor contacts from arcing generating additional heat was designed out. The switches were almost exclusively ceramic bodied. The internal wiring was another point of interest. Where wire was used at all it was so heavy as to be practically rigid, probably an alloy of some description (possibly with nickel). These were preformed into a shape where thermal expansion would be no problem and insulated with a woven asbestos sleeving; today's equivalent would be a woven ceramic. These "wires" would be terminated with an overly large and substantial screw and flat washer. A significant number of heaters had no internal wiring and instead used flat metal strips, again insulated with heatproof sleeving. Later heaters did use multistrand wiring but it wasn't copper - again it was probably an alloy and again covered with a woven insulation and even the terminals were rated for high temperature use. Wire suitable for greater temperatures than 200 C and quite difficult to find but probably the best modification for your smoker would be a little over engineering and specifying wire capable of withstanding 450 C.

1 means the digital thermometer is too cold. Try hitting it with a hair dryer before starting the smoker. Not sure about 4.

You have to hold it down long enough for the safety thermocouple to heat up. If you hold it down for a slow count to ten and it still shuts off, then the thermocouple needs to be changed.
