Rheem Criterion Ii Gas Furnace Not Igniting

The Rheem Criterion II Gas Furnace is a reliable and efficient way to heat your home. However, it is not uncommon for the ignitor in your furnace to fail or malfunction, resulting in the furnace not being able to start up. While temptingly simple to think of replacing the ignition system, the path may be more complicated. Troubleshooting and understanding what might be causing your furnace to not ignite can be an important step in correcting the problem. In this overview content, we’ll discuss some of the potential reasons why your Rheem Criterion II Gas Furnace might not be igniting, and suggest possible solutions that may fix your problem.

Most commonly, if a gas furnace isn’t igniting then one of two things is likely wrong with it: either there’s no power getting to it or the pilot light is not lit. The first thing you’ll want to check is that you have power coming into your furnace so that it has something to ignite and switch on. Once that has been determined, you should go ahead and confirm that the pilot light has been lit prior to switching on the furnace!

If neither of these are causing issues, then there’s potential for other problems like clogged air filters or problems with pressure switches or control boards. Air filters can become clogged over time due to dust accumulation resulting in restriction of air flow; if unaddressed this can cause ignition issues and further hinder regular operation of your gas furnace system. Similarly, pressure switches could be having an issue due to their design which either prevents proper powering up of the thermostat/ignition/gas valve (normally indicating an obstruction in venting), or from faulty wiring which can send false signals telling these parts of the system when they should stay on/off without proper input from user/thermostat. Control boards are also very finicky; they have intricate connections between components of different elements which affects all parts together so identification & calibration need careful attention if troubleshooting is required here by a qualified technician who knows what theyre doing when theyre servicing your gas furnace system!

Last but certainly not least – safety first! Whenever problems arise with any kind of home appliance powered by natural gas, make sure that you are taking all necessary precautions; ensure ventilation in any room where work will happen & wear appropriate safety protection while working around electrical equipment/gas appliances. It’s also important that you let a professional do maintenance work whenever necessary – don’t risk DIY-attempts as this could cause major safety hazards!

We hope this overview content gave you useful information about why your Rheem Criterion II Gas Furnace might not be igniting and how you can go about tackling potential fixes for it!
