What does this symptom mean?
One burner fails while the others work, or the spark operates but no flame appears. 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. Incorrectly seated burner cap or head
Incorrectly seated burner cap or head. Similar symptoms can have different causes, so parts should not be replaced by guesswork.
2. Blocked burner ports or jet
Blocked burner ports or jet. Similar symptoms can have different causes, so parts should not be replaced by guesswork.
3. Moisture or damage at the electrode
Moisture or damage at the electrode. Similar symptoms can have different causes, so parts should not be replaced by guesswork.
4. A valve or gas-flow fault for that burner
A valve or gas-flow fault for that burner. Similar symptoms can have different causes, so parts should not be replaced by guesswork.
Safe checks before booking service
- Shut off gas and allow the hob to cool.
- Reassemble burner parts in the correct position.
- Dry the area after cleaning.
- Compare spark and gas sound with other burners without dismantling internals.
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
- Return burner caps to their correct positions after cleaning.
- Dry the ignition and control areas thoroughly.
- Do not pull the hob from the worktop or disconnect gas yourself.
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.
