marzig20 have same issue at low Temps on my cookshack. The 2 smokers are brother/sister type thing. The issue with them are insulation and air flow. They are so well insulated that at low temps the heating element doesn’t stay on long and then there is the air flow from just a very small vent on the top and a very small grease drain on the bottom.
Another thing that doesn’t help with these units is that they are not PID controlled. What I have done is to take string and tie loops in at at different lengths So I can hold the door open at different amounts to help control air flow. Then I take a mini fan and sit it by the door to keep a constant air flow so my smoke tube doesn’t snuff itself out from lack of oxygen.Randie N said in Smoker modification:

That is a very good idea. I never wanted to actually cut into the smoker. It does such a good job on whole briskets, pork butts, etc

Now I have another crazy idea. As Randie N mentioned, this type of smoker is well insulated and has very little airflow. The heating element is either on high or off. By the time the thermostat shuts the element off there is a lot of residual heat left in the element. As it cools it still continues to heat the smoker raising temps well above the thermostat setting. Not a problem if doing a brisket at higher temps.
Today I found a rheostat dimmer rated for 1,000 watts. The element in the smoker is 700 watts. I think if I plug the smoker into the rheostat and set the smoker thermostat so it is always on I can control how hot the element actually gets. Just like when you adjust the element on an electric cook top. I’ll keep the duct fan on top running continuously to provide enough air flow to keep the smoke tube smoking.
I’m definitely interested in the PK100 but with the small batches I make I can’t justify the cost. Especially when I give 3/4s of what I make away. I guess being retired I just have far too much free time on my hands.

I have a masterbuilt electric. What I did was order a inkbird pid controler. Its capable of 12 stages of temperature and time. I place the inkbird’s thermal sensor just above the heating element after I warm up the smoker. The smoker draws more amps than the inkbird can pass thru so we built a relay box the smoker gets on off power from. The box plugs into the 120 recrptical. The inkbird plugs into a passthrough circuit in the box. The relay ON/OFF switch plugs into the inkbird HEATING/cooler controler and the smoker plugs into the power out on th relay box. I turn the smoker dial to high and start cooking. I can controll the temps down to 120 degrees and as high as 225. The inkbird is only rated up to 240 so I dont go higher. My temp swings when cooking very by about4 degrees with the probe next to but not touching the element. Work fantastics on thermal processing that changes temps often.

Without making modifications to the cabinet to increase air flow, I am not sure if they can be entirely satisfactory for sausage making, even with adding a PID controller, which is a very good first step.
As mentioned, they are about perfect for use as a smoker/oven for briskets, ribs, and butts, but for sausage you just need more air volume for drying, IMO -
Vegas humidity is usually real low so drying is not usually a problem for my tastes but I can see where it has limitations

It’s prewired and can handle the 700 watts of my smoker oven. So far the results are very promising. The best temp control that I have ever had. I’m still struggling with the menu flow with only four buttons. I should probably have one of my grand kids help me with that, LOL. I plan on opening the drain hole in the bottom to aid in better ventilation.

I recently put an inkbird PID controller in a homemade electric smoker. It supposedly has a self-tuning feature. My experience with the self tuning was not very good. Internet reviews backup my experience as well.
After manually tuning the PID, it was holding +/- 2 degrees around the setpoint temperature.Paul

processhead that’s the problem I’m having with the self-tuning. How do you manually tune?

I sold the smoker recently and don’t have the PID handy to check the settings. I’ll see if I can contact the new owner and get the key settings.
Did you get the ITC-106VH? What kind of temperature probe did you use with the controller?

processhead I spent last night and this morning researching on how PID controllers work. I’m thinking that the values you set on the smoker you sold may not work with my “Rube Goldberg” contraption.
Do you think I should reset to factory defaults and then start manually adjusting? First start with the proportional and then the integral values. Will I even have to mess with the derivative value?

I think your observations and plan make sense.
I would start by resetting to the default values. Then make sure that the default temp sensor type matches the one you have.
Next, I would set the Proportional Band (P) to a fairly low value like 1 or 2 and see if you get acceptable control without too much overshoot or undershoot of the temperature.
I would leave I and D alone for the present.Also, you may need to check the temperature sensor (PV) reading against a known accurate thermometer. Sometimes you need to calibrate the PV reading to get an accurate reading. There should be a setting to allow moving the PV reading up or down a few degrees to get it to match the actual temperature. Easiest way is to put the sensor tip in boiling water since you know that will be 210 to 212 degrees depending on the elevation of where you live.

processhead thank you. Trouble now is that the power cord has a GFCI and today it won’t reset.

Its not uncommon for heating elements to develop some leakage between the inner resistive element and the outer metal encasement, which is grounded.
Test if that is the problem by disconnecting the element inside the smoker and see if it still trips the GFCI.
Sometimes you can plug the element into a non GFCI source and get it good and hot, which cooks out any moisture inside that creates the leakage path.
If it is bad enough though, even that won’t work and you need to replace the element.

processhead GFCI won’t reset without anything plugged into the controller. There’s a fuse in the controller and I checked the continuity and it’s fine. Looks like I’ll have to send it back.
Yeah, thats not right. Need to get that controller replaced.

I bought it from Amazon because I could get it quick and it was a complete unit already wired. I’m going to return it for a refund and UPS will pick it up Monday. I was a little surprised when I unpacked it by the GFCI on the power cord plug. I suppose this is to try to limit their liability.
Looks like I’m going to start from scratch now and assemble my own. Any suggestions on a particular brand and what additional components I’ll need? I’m thinking I’ll need some type of project box, a ssr relay, a sensor and a power cord. I don’t want to disconnect the plug on the smoker to wire it. I want to be able to plug the smoker into the box so that I can bring the controller inside when not in use. The smoker stays outside on my deck with a cover on it.

This thread has more information on the parts I used.
I used an Inkbird PID in an enclosure.For a little more money, Auber sells a PID controller with programmable temperature steps. Pretty interesting and I might go that route for my next build.

I’ve been checking out the Auber website. They have two PID controllers with programmable temp steps. The more expensive one has a USB connection so you can program steps with a laptop and save different programs.Both of them offer an option for a self contained 10 amp/1200 watt relay which should be adequate for my 700 watt element. What type of sensor would you recommend? They have a 4 inch K that is recommended for smoker ovens.
