I have an intertherm

Customer Question

I have an intertherm heater installed in2012.
JA: Thanks. Can you give me any more details about your issue?
Customer: Sorry, Red light is constant ON. Heater will not ignite. It just has slight hum when it wants to start.
JA: OK got it. Last thing — HVAC Technicians generally expect a deposit of about $18 to help with your type of question (you only pay if satisfied). Now I'm going to take you to a page to place a secure deposit with JustAnswer. Don't worry, this chat is saved. After that, we will finish helping you.
