Low Temperature Alert – “Check Hopper and Burn Pot” Message

Problem

The stove displays a Low Temperature alert or “Check Hopper and Burn Pot” message.

Customers may also describe this issue as:

• Low temp alarm
• Fire went out
• Stove shut down
• Fire died
• Stove stopped feeding pellets
• Check hopper message
• Check burn pot message

The fire may become weak, reduce to embers, or extinguish completely.

Possible Cause

The Low Temperature Alarm occurs when the stove loses communication with the Proof of Fire switch (POF).

This usually means:

• Fire became too small
• Fire reduced to embers
• Fire extinguished

The most common cause is insufficient pellet feed.

Common Feed Problems

Hopper Running Low

Low pellet level may reduce fuel delivery.

Check:

• Hopper level
• Pellet flow
• Pellet movement toward auger

---

Hopper Lid Left Open

The hopper lid safety switch may stop pellet feeding if the lid remains open.

Verify:

• Hopper lid fully closes
• Lid switch engages properly

---

Pellet Bridging

Pellet bridging occurs when pellets stop flowing properly toward the auger.

This commonly happens when pellet density near the auger becomes too low.

Symptoms:

• Hopper appears full
• Auger starves for pellets
• Fire gradually weakens

Break up pellet buildup and verify pellet flow.

Verify Ash Cleaning Settings

Excessive ash cleaning duration may reduce the fire excessively.

To inspect settings:

1. Press and hold the Enter button (Left Arrow) until Set Data appears.
2. Go to:

#4 – Set Ash Cleaning

OR

#7 – Auto Clean (depending on software version)

3. Verify:

Smart Ash = OFF

Maximum duration:

20 seconds or less

---

Recommended Ash Cleaning Settings

Heat Level	Time Span	Duration	Smart Ash
H01	30 min	10 sec	OFF
H02	30 min	12 sec	OFF
H03	30 min	15 sec	OFF
H04	30 min	20 sec	OFF
H05	30 min	20 sec	OFF

Vacuum Switch Issues

If the stove:

• Ignites normally
• Enters heating mode
• Then stops feeding pellets

The issue may be related to the vacuum switch.

This behavior is a common indicator of pressure switch problems.

Rare Cause – Electrical Interference (EMF)

In rare cases, appliances inside the home may create electromagnetic interference (EMF) affecting auger operation.

Examples may include:

• Tankless water heaters
• High-interference electrical devices

Possible solutions:

• Shielding
• Line conditioner installation

Important Notes

The Low Temperature Alarm usually indicates fuel delivery loss, not a failed igniter.

Always verify:

• Pellet supply
• Hopper condition
• Feed system
• Vacuum switch operation
• Ash cleaning settings

before replacing components.

Escalate To Support If

Contact support if:

• Pellet feed appears normal but fire still dies
• Vacuum switch diagnosis is unclear
• Hopper switch tests good but feed stops
• Low temp alarms continue repeatedly
• Electrical interference is suspected
