What does this symptom mean?
The hob works but the cooker oven does not ignite, heats slowly or cannot reach the selected temperature. 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. Weak oven-burner ignition or blockage
Weak oven-burner ignition or blockage. Similar symptoms can have different causes, so parts should not be replaced by guesswork.
2. Unstable flame due to the safety sensor or valve
Unstable flame due to the safety sensor or valve. Similar symptoms can have different causes, so parts should not be replaced by guesswork.
3. A thermostat or temperature-control fault
A thermostat or temperature-control fault. Similar symptoms can have different causes, so parts should not be replaced by guesswork.
4. Heat loss through the door seal or hinges
Heat loss through the door seal or hinges. Similar symptoms can have different causes, so parts should not be replaced by guesswork.
Safe checks before booking service
- Confirm the oven mode rather than grill-only mode.
- Observe ignition through the door window without reaching inside.
- Visually check door closure and seal condition.
- Note whether the issue is constant or appears after running.
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.
