Heatilator Issues - Please help

[WickedJeep]

Hello,

New member here to hopefully troubleshoot my faulty heatilator model NB4236I.

I was enjoying the fireplace one evening then it just stopped. When I flip the switch on no spark happens. I’ve had two fireplace repair vendors out and so far neither have made headway.

Troubleshooting performed:

I checked the continuity of the switch, checked voltage of power supply. Replaced dexen control module, replaced power supply. Still not working. I sent the parts back.

Company 1: checked switch, ground and then replaced the control module and ignition/pilot assembly. Also tried battery backup. Nothing fixed it so put all old parts back on.

Company 2: checked switch, ground and tried battery backup. They then called heatilator support who recommended replacing the control module. I explained we’ve already tried two but they felt it could still be that.

I paid company 1 $65 and now have paid company 2 $330 so far. This company will charge me another $150 to come out and install the control model which I’m confident won’t fix the issues.

Any advice on what I can check knowing what I have already checked or replaced?

Are you using a wall switch or the tech switch underneath the firebox?
Have you replaced the pilot assembly?
How old is the appliance?

I’m using the wall switch. The unit is 16 years old and the pilot assembly was also replaced.

Have you tried pulling the switch, removing the wires & connecting them together?

Both vendors that came out tried that.

I just wanted to share they the issue has been solved. The problem was the hi limit switch on top had gone bad. Ordered a new one and hooked it up and all is good now.

Hi, I have the same model fireplace. Went dead all of the sudden. Where is the hi limit switch that went bad for you?? How can you tell if the pilot light is on/off? This model is hard to figure out since it’s circa 2006. Any help would be appreciated.
