Troubleshooting: ChefAlarm

Here are answers to the questions our Tech Support team is asked most often about the ChefAlarm.


 

Is the “NO PROBE” indicator suppose to constantly flash when ChefAlarm is not in use? I’m concerned that it will use up the battery when not necessary. I have tried every button and nothing makes it stop flashing.

The “NO PROBE” is a notification to let you know that a probe is not plugged in. Since it is a warning indicator, the flashing is normal. It will not use up the battery.

However, we recommend turning the ChefAlarm off when not in use. This is done by pressing and holding the ON/OFF button on the back of the ChefAlarm for 3 seconds.


 

I tried to test my oven with my ChefAlarm and discovered that none of my Pro-Series probes are registering. The ChefAlarm’s display reads “NO PROBE”. Any ideas what’s wrong? I tested all three probes with my DOT and all are functional.

We would suggest replacing your ChefAlarm’s batteries, as a battery change typically fixes these types of symptoms.

If this does not work, please let our Tech Support team know. They will be happy to help you.


 

I tried to use my ChefAlarm, but it won’t display a temperature. Other portions of the display are completely visible, though. What do I do?

We have found that when the battery is right on the edge of the voltage levels, it will have enough power to show the display. However, when it starts alarming, it pushes it past the threshold to a low battery status. We would suggest replacing your ChefAlarm’s batteries, as a battery change typically fixes these types of symptoms.

If this does not work, please let our Tech Support team know. They will be happy to help you.


I plugged the probe into my ChefAlarm and nothing happened. The display is still dark.

First, make sure that you have turned your ChefAlarm on. The On/OFF switch is on the back of the unit.

If that does not work, we would suggest replacing your ChefAlarm’s batteries, as a battery change typically fixes these types of symptoms.

If this does not work, please let our Tech Support team know. They will be happy to help you.


 

I was recently trying to use my ChefAlarm. I was able to turn it on and set alarm temperatures, but where it should have shown the current temperature, it was simply showing “—-“. It did NOT say “No Probe and the low battery indicator wasn’t showing. Can I fix it?

I purchased this ChefAlarm recently and although it worked well for a few months, it has now begun showing a “NO PROBE” error when the probe is clearly plugged in. Can this be repaired?

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).

Pro-Series Probes Temperature Ranges

  • 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, 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.

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

There are several reasons your ChefAlarm 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 ChefAlarm’s audible alarm no longer works. Is there anything I can do?

We would suggest replacing the batteries to see if that resolves the issue. If that does not help, please contact our Tech Support team.


 

My ChefAlarm worked very well for a long time. However, it just started reporting incorrect temperatures. For example, the temperature of a glass of ice water was 200° F. What should I do?

It sounds like it’s time to replace your ChefAlarm’s batteries. If new batteries do not resolve the issue, it is possible that the probe failed. If this is the case, replacing the probe should fix it.

If these two steps don’t resolve the issue, please contact our Tech Support team so they can assist you further.

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

Judging the accuracy of your ChefAlarm 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 ChefAlarm’s 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.

Please contact our Tech Support team if you need further assistance. They are always happy to help.


 

I just received my 4″ Pro-Series High Temp Straight Penetration Probe. It doesn’t seem to be as accurate as the original (Pro-Series High Temp Cooking Probe 6″ right angle) probe that came with my ChefAlarm.

The new 4″ straight probe reads 30.6 degrees in an ice bath, while the 6″ right angle reads 32.0 degrees. Any suggestions?

While all Pro-Series probes measure temperatures within ± 1.8° F of accuracy, there may be slight differences in the results from probe to probe. If you’d like, you can use your ChefAlarm’s calibration trim feature to adjust for these small differences.

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

Now, when the probe is inserted into the ChefAlarm, 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 ChefAlarm 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.

If you need a new probe, any of our Pro-Series probes will work with your ChefAlarm.

Why did my ChefAlarm melt?

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

The ChefAlarm’s thermometer 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 ChefAlarm thermometer, and place ChefAlarm 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

Could you check to see if you have removed the screen’s protective film? If you have and your ChefAlarm is still not working correctly, please let our Tech Support team know. They will be very happy to help.


How should I care for my ChefAlarm?

The directions for caring for your ChefAlarm are found here.


 

I have a question about the pot clip that came with my ChefAlarm. I can see how to attach it to the side of a pot, but the hole for the probe seems too small. I can only get the probe’s tip through it. What do I do?

The probe clips are designed to “catch” the probe rather than to let it slide through loosely.  This feature allows you to adjust how far the probe’s tip will go into the container to which you’re attaching the pot clip.

This video demonstrates how to use the pot clip.


What is the warranty of the probe that comes with ChefAlarm? 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.
