Heat won't shut off sometimes and radio won't work when it happens?

If your heat won't shut off and the radio also stops working intermittently, it may indicate an electrical issue, such as a blown fuse or a faulty relay affecting both systems. It's also possible that a malfunctioning thermostat is causing the heating system to misbehave. Checking the fuse box and ensuring all connections are secure can help diagnose the problem. If the issue persists, consulting a professional technician is recommended to ensure safety and proper repair.
