Ans: As the first step, you need to check out for some common things that could generally be faulty in the heating process. Check the pilot light and the gas and see if both of them are switched on. If you find the pilot light off, you may troubleshoot and relight it yourself as explained previously. After you are done with lighting the pilot light, check the thermostat. There is a great possibility for the issue to reside here as the thermostat is a lot more prone to malfunction. If you still face the problem, you may connect with the company’s care for further assistance.
