Review: Exact model for the Heat and Glo fireplace. Thanks for supplying. It works and fits perfectly I have heat again. Thank you.
Review: My Heatilator gas fireplace's pilot light was not staying lit when I let go of the pilot button no matter how long I kept it depressed while the flame was lit. After testing the thermopile and thermocouple it was clear that I needed a new thermocouple, and this replacement part fit perfectly and does the job as expected.

## Questions & Answers

**Q: will this replace the Mod# ND3933 Thermocouple?**
A: i can't say for sure, but i took my old part out of the fireplace and compared it to the image online- they matched up perfectly- not hi-tech, but it worked for me

**Q: Will this replace dt-500cmn**
A: Maybe. If your pilot flame spreader looks like a three way water slide (made by PSE for Honeywell) then yes. If you flame spreader looks like a round space ship, no.

**Q: Will this work for a Regency P36D?**
A: I dont know!  I used it for my Dovre 400 stove and it was a perfect fit!

**Q: How long is the probe - not the entire thermocoupler.**
A: Probe is approximately 3" long.
