What does this symptom mean?
The flame is shorter than normal, yellow, uneven around the burner, or leaves soot on cookware. The symptom alone does not identify a failed part because several causes can produce the same behaviour. Proper diagnosis considers when the fault occurs, appliance model and whether it is constant or intermittent.
Likely causes
1. Partially blocked burner ports from grease or food residue
Partially blocked burner ports from grease or food residue. Similar symptoms can have different causes, so parts should not be replaced by guesswork.
2. Incorrect burner-cap position
Incorrect burner-cap position. Similar symptoms can have different causes, so parts should not be replaced by guesswork.
3. An air-gas mixture or supply-pressure issue
An air-gas mixture or supply-pressure issue. Similar symptoms can have different causes, so parts should not be replaced by guesswork.
4. A jet or valve problem requiring measurement
A jet or valve problem requiring measurement. Similar symptoms can have different causes, so parts should not be replaced by guesswork.
Safe checks before booking service
- Turn the burner off, allow it to cool and clean ports gently.
- Reassemble parts correctly without enlarging openings.
- Compare flame colour across several burners.
- Check for spills covering part of the burner.
How a technician diagnoses the fault
The inspection begins by confirming the reported behaviour and safely testing the affected function. The technician then compares operation with model specifications and measures related components where required. The purpose is to find the root cause rather than replace the first part associated with the symptom.
| Inspection stage | What is checked? |
|---|---|
| Confirm the symptom | Reproduce the fault and identify timing and affected function. |
| External inspection | Assembly, cleanliness, moving parts, ventilation and visible connections. |
| Technical measurements | Test model-specific components related to the fault. |
| Post-repair test | Operate the appliance and confirm safety and stable performance. |

This is a list of possibilities, not a final diagnosis. Any part must match the model number and inspection result because a similar appearance does not guarantee identical dimensions, connections or ratings.
How to reduce repeat faults
- Clean burners only after cooling and dry them before reassembly.
- Do not force controls or attempt to dismantle them.
- Watch flame colour and stop use if gas odour or abnormal flame appears.
When to call Glem Gas maintenance
Call when the fault repeats after safe checks, when there is gas odour, abnormal heat or noise, or when access requires dismantling the appliance. Have the model number, symptom and governorate ready.
