Rheem Water Heater Igniter Not Working

When i press the ignitor with pilot depressed i get no sparks after about forty tries in a dark room.
Rheem water heater igniter not working. I have a spark ignitor that fails to spark on a rheem gas heater 10 years old. When it is working properly it generates a small electrical current to keep the gas valve opened when heated by the flame. It is a small bulb shaped device located near the pilot aperture. Rheem manufacturing ranks as the global leader in the manufacture of high quality sustainable and innovative water heaters tankless water heaters air conditioners furnaces pool heaters and hvac systems for residential and commercial applications and is a full member of ahri the air conditioning heating refrigeration institute.
Is age a probable factor. A common problem with rheem water heaters is a loose thermocouple that falls slightly out of position. 1 see all buying options add to my list rheem sp10972 hot surface ignitor. My dad used it to fix our hot water heater and its working good.
