Manual for majestic gas fireplace model HDV36 RN

SOURCE: GAS FIREPLACE

Yes, hopefully changing the thermocouple (skinny sensor) or thermopile(fat sensor) would do the trick.
Start with these fairly inexpensive repairs first.
Unfortunately if the honeywell valve is bad a new one can be expensive.
Also it is hard to order parts from Majestic, they just went bankrupt, not to long ago and Martin is taking them over. You might look for your valves model# and check online for other suppliers of that model# or ask for a compatible Direct Vent gas valve that's not as problematic. (eBay and HVAC dealers, etc.)
FYI:
You said it's been about 5 years, you might decide it's less of a hassle to have new gas fireplace installed. Martin and Empire are probably two of the best, with 5 year parts and labor warrantys.
Hope you find some success in your endeavor.
