Troubleshooting: Signals

Here are answers to the most common technical support questions about Signals.


What power adapter may I use to charge Signals?

Signals requires a 12 volt power adapter. Make sure you do not use another type of adapter as other voltages will cause damage. Voltage information can be found on the back of each power adapter.


How do I set up my Signals?

To set up your Signals, download the free ThermoWorks BBQ app from either the iTunes App Store or the Google Play Store. Install and open the app on your smartphone or tablet and follow the onscreen instructions to add your new Signals to the app. Additional information can be found in the ThermoWorks BBQ app and in the online help file, located here.


How do I set up Signals alarms?

Signals includes both High and Low alarms. Both alarms sound on the hardware and on the phone or tablet. You may set the alarms on both the hardware or in the ThermoWorks BBQ app. Additional instructions can be found in the ThermoWorks BBQ app and in the online help file, located here.



How far away can I take my phone from Signals to get a reading?

Signals will communicate with your phone or tablet via Bluetooth up to 95 feet line-of-sight unless other factors are involved.

  • Devices that use 2.4GHz radio frequencies (microwave ovens, cordless phones, remote controls, etc.) may create interference.
  • The Bluetooth signal may be interrupted by walls and building materials, such as tinting on windows.

Signals will communicate with your phone or tablet via Wi-Fi anywhere in the world as long as Signals has access to a strong Wi-Fi connection and your phone or tablet has an internet connection to receive the data (Wi-Fi or cellular)


Where can I find instructions for my Signals?

Download your Signals Operating Instructions here to learn how to adjust the settings, see recommended food safety temperatures, and more.

Download the High Temp Probe Rings instructions here.

Instructions for using the ThermoWorks BBQ app (such as recording and graphing temperatures and changing the measurement intervals) are found in the app and in the ThermoWorks BBQ app and in the online help file, located here.


My Signals thermometer is not working. All I seem to get is a flashing “NO PROBE” in one of the channels. The probe is inserted correctly. Any clue what’s wrong?

It is possible the probe has failed. If this has happened, a new probe will resolve the issue.

The most common reasons for probe failures include:

  • The probe has been used outside of the recommended temperature range. Keep the probe cable away from oven elements, flames, coals, grill or oven racks—all of which can reach temperatures far higher than 700°F (even if an oven/smoker is set lower).

  • The cable got wet. When you’re cleaning your probe, you can carefully wipe down the stainless steel cable as long as you don’t submerge it in liquid. You might find it easiest to clean the cable with our probe wipes.

  • Excessive wire kinking.

Pro-Series Probes Percautions

Avoid grilling or broiling with your probes unless you protect your probes, as these high-heat methods usually involve temperatures above your probe’s specifications. Instead, we recommend that you use an instant-read thermometer—such as a Thermapen or a ThermoPop—while grilling or broiling.

Here is an article with great suggestions on how to prolong the life of your Pro-Series Probe.

My Signals is displaying an LLL (or HHH) error. What does this mean?

There are several reasons your Signals may display either an LLL or HHH error, the most common being that the probe wire was damaged or broken.

If your Pro-Series probe was exposed to temperatures above or below its temperature range (-58 to 572°F  or -50 to 300°C), you will see one of these errors. LLL means that the probe was exposed to temperatures below its range and HHH means that it was exposed to temperatures above its range.


 

My Signals is not reading food temperatures accurately. What’s wrong?

Judging the accuracy of your Signals in food or air can be difficult. The best way to verify the accuracy of a probe or digital thermometer is with a proper ice bath test. This can be done quickly and easily at home with the instructions found here.

If your Pro-Series probe is accurate, it will read within ± 1.8°F of 32°F (30.2 to 33.8°F). If it is reading accurately in this test, you can rest assured that it is reading accurately in food and at higher temperatures.

Last night, as I monitored some steaks I was searing on the grill with my Signals, something went wrong. I think I may have gotten a probe too hot.

Now, when the probe is inserted into the Signals, it reads a temperature very briefly before a “NO PROBE” error pops up. Is the probe ruined?

It sounds like your probe failed as it was exposed to the very high temperatures that accompany grilling.

  • The Pro-Series probe that comes with Signals has an operating range of -58 to 572°F.
  • Flare-ups associated with grilling can easily reach temperatures above 1000°F, which can damage the probe.

This is why we we don’t recommend Signals for grilling unless you protect your probes. It was designed to track temperatures over an extended period of time with moderate-heat cooking methods such as smoking meat, oven-roasting, deep-frying, homebrewing, and Sous Vide.

Instant-read thermometers, such as a Thermapen MK4 or a ThermoPop, are the best choice for monitoring temperatures when you are using high-heat cooking methods such as grilling or broiling.

Why did my Signals melt?

It is likely that your Signals thermometer (the hardware) was exposed to temperatures above its operating range, which is 32 to 122°F (0 to 50°C).

The Signals hardware does not go in the oven when you use it, as high heat will melt it. It should not be attached directly to a smoker or grill.

Instead, insert the Pro-Series probe’s tip into the food you are tracking, connect the other end of the probe to Signals thermometer, and place Signals outside of the oven/smoker (usually on a countertop). Place the food in the oven/smoker and close the door on the cable.

Closing the oven door on the probe’s cable won’t hurt it. Because the cable is thin, your oven, grill, or smoker won’t lose any heat

I just received my new Signals. I can’t change the temperatures. What do I do?

Could you check to see if you have removed the screen’s protective film? If you have and your Signals is still not working correctly, please contact our Tech Support team.


 

How should I care for my Signals?

  1. The best way to extend the life of your Signals hardware is to clean it properly after each use. Wipe it off with a damp, soapy cloth or paper towel. Do not submerge it or put it in the dishwasher.
  2. Your Signals should not be affixed directly to a smoker or grill’s lid or left in the smoker or oven. The high heat will melt the plastic housing.
  3. Avoid having the thermometer’s LCD screen in direct sunlight for an extended amount of time as this can damage the display.

 

How should I care for Signals’ probes?

  1. To clean the probe, carefully wipe down the stainless steel cable with a slightly damp, soapy cloth or paper towel. Do not put the probe in the dishwasher or place the entire probe in a sink of water. Submerging the cable can cause damage.
  2. Your Pro Series probe’s operating range is -58 to 572°F. Keep the probe and cable away from oven heating elements, flames, coals, grills, or racks—all of which can reach temperatures far higher than 700°F (even if an oven or smoker is set lower).
  3. The probe should not be attached directly to a rack. The high heat of the rack will cause damage to the probe, transition, and cable. Use a grate clip.
  4. Do not pull on the probe’s cable. Use the molded transition.
  5. While the cable may be closed in an oven door or under a BBQ hood, avoid pinching the probe’s cable between very hot surfaces, such as a cast metal grill hood, without some insulating protection. Use an access hole if available.
  6. Store your Pro-Series® probe with the cable free of kinks and lightly coiled, wrapped, or hung loosely.

 

What is the warranty of the probes that comes with my Signals? I think mine isn’t working correctly.

Pro-Series probes come with a 6-month warranty. Please let our Tech Support team know if you need help with yours.
