Propane BBQ Grill, Firepit, Fireplace Thermocoupler Sensor M8x1
This Earth Star replacement thermocouple is marketed for grills, firepits, fireplaces, and general propane appliances. The listed thread is M6 x 0.75 (note product text also references M8x1 in some descriptions), and the total length is 600mm/24 inches. The unit specification shows a generated voltage of >20mV and a valve opening time under five seconds, which indicates it is designed to reach operating voltage quickly when heated.
Use-case considerations: match the thread and length to your appliance and verify whether M6 or M8 thread is required. The relatively common 24″ length may suit many grill and patio heater pilot assemblies where space allows.
Outdoor Heater Replacement Thermocouple & Tilt Switch Kit
The havyduti kit combines a thermocouple and tilt (dump) switch intended for round stand-up and pyramid patio heaters. Its features emphasize safety: automatic shutoff in the event of tip-over, flame-out, or low-oxygen conditions. The product states it is suitable for “most outdoor round stand up propane heater and pyramid patio heater” models and undergoes quality inspection.

Use-case considerations: choose this kit when you need both the sensor and the safety tilt switch. It is targeted at outdoor standing heaters where a tilt-detection mechanism is required for regulatory or manufacturer safety compliance.
IDEASURE Patio Heater Thermocoupler & Dump Switch 13.8″
The IDEASURE kit lists a 13.8″ thermocouple with an included dump (tilt) switch, designed to address pilot light issues where the pilot will not stay lit. The product description highlights compatibility with a range of outdoor heater styles—standing patio heaters, tower glass tube heaters, and some table heaters including Hampton Bay models.
Use-case considerations: the shorter 13.8″ length fits heaters with compact pilot assemblies. The listing also mentions an easy installation approach—connecting two leads to bypass—so it may be suitable for DIY repair of common patio heater pilot problems.
098514-01 Propane Thermocouple Replacement For Desa Heaters
This Piumeif-listed replacement identifies as 098514-01, compatible with many Desa and vent-free wall heater models. The part is promoted as a high-temperature thermocouple with 39″ length and compatibility references to specific model numbers such as CGN18, CGN10, and related series. It is intended for ventless gas fireplaces, wall heaters, and gas log sets.

Use-case considerations: this product targets homeowners or technicians replacing thermocouples in vent-free wall units or specific Desa models. Confirm model compatibility and required length before ordering; the long 39″ length suits installations where the thermocouple must route further from the pilot location to the gas control.
Joyzan Universal Gas Stove Thermocouple Kit (900mm)
The Joyzan kit is a universal-style thermocouple assembly marketed for stoves, fireplaces, pizza ovens, boilers, and heaters. It lists a 900mm (35.4″) length and includes five nuts to fit various valve fittings. The head size is specified as M6 x 0.75 and the kit touts high temperature resistance (over 700°C capability).
Use-case considerations: this kit is meant for broad compatibility and multiple head fittings, making it a candidate when the heater model is unclear or when you need a longer thermocouple with several adapter options. Verify thread and connection type on your valve prior to installing.
Buying Guide: How To Choose The Right Propane Heater Thermocouple
Selecting the correct thermocouple or repair kit depends on several technical and application-specific factors. Below are the key considerations to compare products objectively.
Thread Size And Fitting Type
Thermocouple connection threads commonly include M6 x 0.75 and M8 x 1 among others. Confirm the valve or pilot assembly thread spec before purchase. Universal kits with multiple nuts can cover several thread sizes but always verify fit to avoid returns.
Length And Routing
Thermocouple lengths vary from under a foot to over three feet. Measure the distance from the pilot flame to where the thermocouple attaches to the gas control. Too short a unit will not reach; too long may require careful routing to avoid kinks or heat damage.
Compatibility With Appliance Type
Match the thermocouple to the appliance: patio heaters and standing units often require integrated tilt/ dump switches, while RV water heaters and vent-free wall heaters may require model-specific assemblies. Manufacturer part numbers (e.g., 098514-01) are useful for cross-referencing compatibility.
Inclusion Of Safety Switches
Patio and tower heaters often include a tip-over or dump switch as part of the safety interlock. Kits that integrate a thermocouple and tilt switch provide both flame detection and tip-over protection—important for compliance and safety.
Voltage And Response Characteristics
Thermocouples generate millivolt signals when heated. Some listings specify voltage output (for example, >20mV) and valve opening response times. Faster voltage rise and reliable millivolt output ensure the gas control senses the pilot flame and remains open when appropriate.
Material Durability And Heat Rating
High-temperature environments require thermocouples rated for elevated temperatures. Stainless steel or plated materials and descriptions noting temperature resistance (some state hundreds of degrees Celsius) are preferred for long service life.
Ease Of Installation
Look for kits with clear installation notes and included adapters if needed. Some universal kits list multiple nuts and adapters to simplify fitment. Be cautious when bending thermocouple tubing—sharp bends can pinch internal wires and cause failure.
Model-Specific vs Universal Kits
- Model-Specific Parts: Often plug-and-play for a given heater series and reduce uncertainty about fit and performance.
- Universal Kits: Offer flexibility with adapters and longer lengths but require checking thread sizes and possible bracket modifications.
Safety And Testing
After installation, verify pilot flame stability, thermocouple voltage (if you can measure millivolts safely), and that any tilt/dump switch reliably interrupts gas flow when actuated. Follow manufacturer instructions and local codes for gas appliance servicing.
Comparison Perspectives
- For Patio Heaters: Prioritize kits with a tilt/dump switch (havyduti, IDEASURE).
- For Vent-Free Wall Units: Choose model-specific replacements with the correct part number and length (Piumeif 098514-01).
- For Broad Compatibility: Consider universal kits with multiple nuts and long lead length (Joyzan).
- For Grill/Firepit/General Use: Look at M6/M8 thread compatibility and medium-length options (Earth Star).
Final practical notes: always shut off gas supply and follow appliance-specific disassembly steps. If unsure about gas fittings or safety interlocks, consult a certified technician. Proper fitment, safe routing, and secure connections are essential for system reliability and safety.
