What should I report if a shutdown followed renovation?
Explain what changed and when. Keep a record of the furnace alert. Work done before a shutdown may be a clue, but the timing does not prove the cause.
Record the symptom
Say whether the work moved the cabinet, closed in a space, changed a ceiling or involved the roof. Report only changes you know about. Do not open new finishes or climb to a vent outlet to find more details.
Keep the heating pattern separate from the work history. Did the furnace stop as it tried to light, or after it had warmed the rooms? Leave model-specific tests and any restart decision to a trained technician.
Plan the access
Bring any record of the work and its permits. If a new wall or cupboard now surrounds the furnace, explain that before the visit. The check may need an access plan before any finish is opened.
The county has a process for heating and gas work done without required permits. If this issue comes up, ask the building office about the record. A guide or service call cannot grant a permit.
Define the repair decision
Ask whether the remedy concerns a furnace component or a condition created around the installation, such as access to an affected vent or fuel route. Require the finding supporting that distinction.
If the plan includes building work, ask who will do it and which permits it needs. Settle what must happen before heat can resume. Keep the unit off if you have been told it is unsafe.
Questions about this repair
Can I open a new cupboard around the furnace to make it run?
Do not alter the enclosure as a trial repair. Have the installation assessed and follow instructions for safe use and any required correction.
