So it really depends on the situation and this is also why trip insurance is so important. Personally - while an inconvenience a broken fridge would not warrant having to stay in a hotel - usually. If it’s something that’s a safety hazard or a major issue - then it depends on what caused the issue. If a renter left the door open during a storm and the door blew off - that’s on them. If it’s just a mechanical breakdown, wear and tear etc that the renter did not cause, then it’s something I would consider paying for. But again on any lengthy, far away, or higher priced rental, I would really encourage the renter to buy trip insurance.
