Furnace causes vibration or rumbling transmitted through the house

Safety: Turn off power before tightening any screws or brackets.

• Tighten casing screws: Check all accessible panel screws on the Vokera furnace and tighten them.
• Check mounting: For wall-hung units, ensure the wall bracket is secure and the unit is firmly seated.
• Inspect nearby pipework: Make sure pipes are clipped and not touching walls or structures that can amplify vibration.
• Call technician if fan-related: If the vibration seems to come from the fan, the fan may be unbalanced or failing and should be inspected by a professional.
