Make Sure You Test Your Furnace or Heat Pump Early to Make Sure It Is Working Properly.

Troubleshooting Gas & Electric Furnaces

Hi Everyone! We would highly recommend that you test your furnace or heat pump on a cool fall evening to make sure that your furnace or heat pump is working properly. We do not recommend waiting until the weather gets really cold out before testing your heating and air conditioning equipment because this could result in a really cold house or an expensive repair service call. We recommend having an extra furnace hot surface ignitor and flame sensor on hand. We sell furnace hot surface ignitors on the following page: Please click here to see the name brand furnace hot surface ignitors we sell. Please click here to see the name brand furnace flame sensors that we sell.

You might even want to keep an extra furnace pressure switch too. Please click here if you are interested in the furnace pressure switches that we sell.

If you would like to look up any parts for your furnace or heat pump please send us your furnace or heat pump’s brand name and model number and we will be happy to look up and recommend parts for you! Our email address is support@arnoldservice.com

Below we have two real good Youtube videos. One is from Word of Advice TV titled “Is Your Furnace Not Working Right? How to Check it Yourself.”

Another great YouTube Video called, “Furnace Troubleshooting” by Structure Tech Home Inspections.

Do not test a pressure switch by sucking on the pressure switch tubing.

I wanted to post this because many people are telling me that they are sucking on the pressure switch tubing to test pressure switch operation. I have heard from other forums that you should not suck on the pressure switch to test it because this can damage the diaphragm inside the pressure switch. It would be best to use a manometer or test with a volt meter like we advise on the following page: https://arnoldservice.com/how-to-test-and-troubleshoot-gas-furnace-pressure-switches/ I wanted to pass this along so others will not damage pressure switches. Please feel free to comment below.

Always allow electronic parts to warm up to room temperature before applying power.

Rheem Ruud Furnace Control Board 62-25338-01

I remind myself of a terrible experience I had several years ago when I brought my desktop computer in from a cold car, plugged it in and fried the mother board! I found out the hard way that it is always a good idea to allow an electronic part like control boards, pressure switches, televisions, laptops, etc. to warm up to room temperature before applying power. If you bring anything in from the cold outdoors into a warm home, condensation (water) will form on the part. We all know that water is a conductor. We can see why so many electronic parts can get destroyed if we do not allow them to warm up before applying power.  I would strongly suggest that we allow the electronic parts and devices to sit for a couple of hours for warm up. This allows time for the water condensation to evaporate before applying power. I hope this will save you and others from problems.
