HEr Error Code

What Is an HEr Error?

HEr stands for High Error Reading and is an error specific to non-WiFIRE grills with 3-digit, Digital Controllers.

An HEr means that your grill's temperature exceeded 550°F/287°C, usually due to a grill fire/flare up. When your grill reaches over 550°F, the grill will automatically shut off as a safety precaution, and the controller will display "HEr." 

Common Causes

An HEr error occurs when a grill's temp rises over 550°F/288°C, usually due to one of the following:

• Grease Fire 
• Lack of grill maintenance
• An unresolved LEr error on a previous cook
• Incorrect startup or shut down procedures
• Heat Baffle or Drip Tray installed incorrectly

How to Resolve an HEr Error

In most cases, the HEr error will clear once you restart your grill. Let's walk through a quick, grill health check first to make sure another underlying issue isn't at hand.

1. Turn off and unplug your grill. If the grill is still hot, proceed with caution or wait to proceed until the grill cools off. 
2. Did you get the HEr error after having a grease fire? 
   Because an HEr is triggered when the grill's temperature exceeds 550°F/288°C, grease fires are the most common cause for this error.
   • Give your grill a thorough cleaning to make sure your grill is in good condition to continue grilling.
3. Make sure you're following the correct startup and shutdown procedures.
   • Shutdown: If your grill was not shut down correctly on the last cook, there may have been excess pellets in the firepot. Too many pellets in the firepot can cause them to combust all at the same time, spiking the grill's temperature upon ignition.
     • This occurs most often when a grill had an LEr error during the previous cook session.
4. Check if your Drip Tray and Heat Baffle are installed correctly and are undamaged. 
   • Drip Tray: Incorrectly installed Drip Trays can cause grease to direct into the barrel and not into the grease drain and bucket as designed. Look for rust holes (not just surface rust) and poorly installed Drip Tray Liners that could cause grease fires.
   • Heat Baffle: Incorrectly installed Heat Baffles can misdirect heat from the Firepot and cause the grill to get much hotter than it's designed to withstand. If incorrect, install correctly. 
5. Check if the RTD is damaged or touching another part of the grill.
   1. If there is no damage and the RTD is not touching another part of the grill, continue to 8. Check the RTD connection to the controller below.
   2. If touching another part, gently bend the RTD away from the wall or object it touches and continue troubleshooting.
      1. If there was not a fire, go through a brief, preheat cycle to confirm that the RTD is not reading higher temps incorrectly by looking for erratic temperature jumps.
      2. If the temperature rises normally, the RTD is fine. The HEr was likely caused by a small drip tray flare up. 
      3. If you get an HEr prior to reaching 550°F/288°C, contact Customer Support.
   3. If damaged, let's proceed to check if it's reading temp correctly to see if the damage is causing issue.
      1. If there was not a fire, go through a brief, preheat cycle to confirm that the RTD is not reading higher temps incorrectly by looking for erratic temperature jumps.
         1. If the temperature rises normally, the RTD is fine. The HEr was likely caused by a small drip tray flare up. 
         2. If the temperature jumps around or if you get an HEr prior to reaching 550°F/288°C, contact Customer Support.
6. Check the RTD connection to the controller: 
   1. Turn off and unplug the grill.
   2. Unscrew the controller. Disconnect and reconnect the RTD from the controller.
            
   3. Plug in and turn on the grill. If you still get an HEr, give Customer Support a call to get set up with the right part.
