Overview

This OEM ignition kit covers the hot surface igniter (part number 1172533, IGNITOR HSI) and the matched snap-mount gas valve (part number 1175705, VALVE N HSI SNAP HW VR8205S) for the Tempstar T8MPN100F20B2 gas furnace. The HSI glows hot to ignite the burners on a call for heat, while the Honeywell VR8205S gas valve meters the gas supply and opens only when ignition conditions are safe. Together they form the heart of the furnace's ignition sequence — a failure in either causes no-heat or short-cycling lockouts.

Compatibility

Direct-fit for the Tempstar T8MPN100F20B2 and other ICP/Heil/Comfortmaker furnaces using the 1172533 HSI and the VR8205S-style snap-mount gas valve (part 1175705). Confirm both part numbers and the valve's snap-mount configuration before installing.

Installation Guide

  1. Safety First — Disconnect power at the switch and breaker, shut off the gas supply, and verify zero voltage with a multimeter.
  2. Access — Remove the burner-compartment service panel.
  3. Document — Photograph the igniter position, valve wiring, and gas-line connections before disconnecting.
  4. Remove — Unplug and unscrew the old igniter (handle by the ceramic base only); disconnect the valve wiring and gas line, then remove the old valve.
  5. Install — Mount the new gas valve with proper thread sealant on gas connections, seat the new igniter in the flame path, and reconnect all wiring per your photos.
  6. Test — Restore gas and power, leak-check all gas joints with soap solution, then run a heat cycle to confirm ignition and steady burner flame.

Signs You Need a Replacement

  • Blower runs but burners never light (no-heat).
  • Igniter is cracked or reads open on a meter.
  • Gas valve clicks but no gas flows, or stays open improperly.

Frequently Asked Questions

Does this Igniter fit my Tempstar T8MPN100F20B2 — OEM 1172533 / VR8205S | Ships Today?
Yes. This is the factory-specified OEM igniter for the Tempstar T8MPN100F20B2 — OEM 1172533 / VR8205S | Ships Today. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the igniter on my Tempstar T8MPN100F20B2 — OEM 1172533 / VR8205S | Ships Today?
Difficulty: Medium (20–30 min)
Step 1: Turn off power and gas. Step 2: Open furnace panel. Step 3: Locate igniter near burners. Step 4: Disconnect two-wire plug. Step 5: Remove mounting screw. Step 6: Install new igniter — do NOT touch element with fingers. Step 7: Reconnect, close panel, restore power/gas.
My furnace won’t ignite. What part is bad?
Furnace won’t ignite after the draft inducer runs = failed igniter. The hot surface igniter should glow bright orange within 60 seconds. No glow = cracked/burned out. Weak glow = degrading. Average lifespan: 3–7 years. Replacement: $15–$40 DIY.
Is this igniter compatible with Bryant or Payne too?
Many Tempstar parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Tempstar igniter?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
