Heater won't stay lit
For model number MH55FAV
Hello Eleanor, thank you for your question. We found a few things that you can check for. If the heater is overheating due to poor airflow or other issues, it may have a safety feature that shuts it off to prevent damage or fire. Or, it may have faulty wiring, tripped breakers, or blown fuses. These can interrupt the power supply to the heater. We hope this helps.
