Accordingly, why does my heater start and stop?
A furnace that starts then stops is a common issue also known as short cycling. When the furnace cycles more often than this, short cycling is possible – it may also be possible that extreme temperatures are causing the need for more frequent cycles, or your furnace is undersized or requires additional insulation.
Subsequently, question is, why does my heater turns off before reaching temperature? A lack of airflow can cause your furnace to stop heating before reaching the set temperature. Check that registers are open, no ducts are damaged or crushed and replace your furnace filter. Inside your furnace should be clean and free of debris, especially around the blower motor and the heat exchanger.

Why does my furnace turn off after a few minutes?
A common reason a furnace short cycles is because the heat exchanger, the part that heats your air, is getting too hot due to a lack of airflow. Once the heat exchanger overheats, it trips the high limit switch, which shuts the furnace down to protect it.
