Gas fireplace


Not sure if proper location for question but here goes. Have replaced the wall switch for gas fireplace a few times so far. Works for a few weeks then stops working to turn on gas fireplace. Pilot stays lit, just won't give full fire to unit. Is there a smaller switch that should be used because of lower voltage to the solenoid unit?

Can you post pictures of the solenoid where the wires hook up. Do you know if this is a millivolt unit, or does it have a 24vac transformer to it?

Gas fireplace


Transformer run gas fireplaces are rare. Thermocouple and millivolt systems are the norm. Thermocouple systems won't run a wall switch.
Your problem with the wall switch will usually be related to a low voltage output by the powerpile generater or a poor set of wiring/connections that are causing too much resistance to the 1/2 volt that runs the gas valve.
First make sure that every wiring connection is completely tight. That means all the electrical connections on the gas valve , wall switch and possible limit controls. Sand the contact connections clean if they look dirty.
Next you can try dislodging any debris that might be limiting the pilot flame from properly enveloping the powerpile. This is as simple as tapping the metal base of the pilot assembly with a large screwdriver while the pilot is running. The vibration of your tapping combined with the pilot gas pressure will often be enough to clear the pilot flame. If the pilot flame becomes larger or harder, stop tapping, you've done it. Some powerpile systems have pilots that have a small air intake near their base or behind a small grill that fill up with dust and need to be blown clean. Use some small tube or long straw for this.
If you have a bunch of connected extra thermostat line coiled under your fireplace or behind the wall switch, shorten it to just what you need.

Let us know how it goes.
