No. A laundry bag can limit contact and tangling, but it does not change the temperature, water exposure or mechanical treatment allowed by the item's care label.
Understanding this situation
An unsuitable fibre, glued decoration, loose component or dry-clean-only finish can still be damaged inside a bag. The bag itself also has to suit the programme and must not be stuffed so tightly that the contents cannot move or rinse. Its role is protection within an already permitted washing method.
A useful next step
Choose the fabric-compatible cycle first and use a bag only where appropriate. Check that small items cannot escape through a damaged closure. If a delicate piece changes shape or finish, retain the label and wash details rather than concluding that the machine is necessarily overheating; the bag does not rule out a care-method mismatch.
