What Our Furnace Ignition Repair Includes
Every ignition repair visit covers diagnosis, the failed part, and verification that the furnace lights and holds.
Work order
Furnace Ignition Repair- Full ignition diagnosis: We watch a complete ignition cycle and meter the igniter, flame sensor and gas valve. You get the actual readings, not a guess, and we tell you which part failed and why.
- Failed part replacement: Hot-surface igniter, flame sensor, thermocouple or control board, replaced with a part matched to your furnace model. We carry common igniters for Carrier, Trane, Goodman, Rheem and Lennox on the truck.
- Three-cycle verification: After the repair we run the furnace through three full heating cycles to confirm the burners light and hold every time. A furnace that lights once and fails on cycle two is not fixed.
- Combustion check: A combustion analyzer confirms the flame is burning clean and the flue is drafting correctly. This catches gas pressure problems that would otherwise shorten the life of your new igniter.
- Safety inspection: We check the heat exchanger for cracks, test the limit switch and inspect the flue. Ignition faults can mask carbon monoxide risks, and this sweep catches them while we are already on site.
- Parts and readings record: You get the old part, the meter readings and a written note of what was replaced. It goes on your address history so the next tech starts with facts instead of a blank slate.

Furnace Ignition Repair Severance CO: What It Really Involves
An ignition fault is a small part failing at the worst time. We meter it, prove it, and fix the actual cause so the furnace lights on every cycle, not just the first one.
Furnace Ignition Repair Severance CO is the diagnostic and repair work that restores the ignition sequence inside a gas or propane furnace: the hot-surface igniter, the flame sensor, the gas valve and the control board all have to fire in order. When any one of them fails, the burners never light and the blower pushes cold air. We test each component with a multimeter and manometer, confirm the reading against the manufacturer spec, and replace only the part that actually failed.
Most calls we run in Severance start the same way: the thermostat calls for heat, the inducer spins up, and nothing ignites. Sometimes the igniter glows but the flame drops out three seconds later because a dirty flame sensor can't prove combustion. Other times a cracked igniter reads open on the meter. If your furnace won't ignite in Severance CO, we can usually tell you which part failed within the first 20 minutes on site.

Our Furnace Ignition Repair Process
Five steps, start to finish. Here is exactly what happens when you book ignition repair with us in Severance.
Tools and Methods We Use
Each method answers a different question. Together they leave very little to guess.
Measures gas manifold pressure so we can confirm the valve is delivering the right pressure for clean ignition, especially on propane systems where the spec is tighter.
Checks flue gas oxygen, carbon monoxide and temperature after the repair. It confirms the flame is burning clean, not just burning.
Reads millivolt output on standing-pilot furnaces. A weak reading explains why a pilot will not stay lit even when the flame looks fine.
Verifies draft and detects spillage on natural-draft furnaces, which matters when ignition problems trace back to venting.
When to Call for Ignition Repair
A Severance homeowner wakes up to a 58-degree house and a furnace that clicks every few minutes without lighting.
We book a same-day ignition repair, meter the igniter on arrival, and replace it if the reading is open.
HomesA rental property in Windsor has a furnace that lights, runs 30 seconds, then shuts off and retries.
We diagnose the flame sensor first, since short-cycling after ignition almost always traces there.
BusinessesA commercial building in Greeley has a rooftop unit that has thrown an ignition lockout code three times this month.

BusinessesA homeowner in Eaton is selling their house and the inspection report flags intermittent ignition on a 12-year-old furnace.
We run a full ignition diagnostic, document the readings, and repair or replace the failed component.

How Ignition Repair Works in Severance
Severance sits at about 5,000 feet in Weld County, and that elevation changes how a furnace burns. The thinner air means ignition components work a little harder, and a marginally weak igniter that would survive at sea level can fail here in January.
Downtown Severance
Older homes near the center often have original furnaces with standing pilots and thermocouples. We keep thermocouple testers and replacement pilot assemblies on the truck for these calls.
Severance residential subdivisions
Most homes here were built between 2000 and 2020 with high-efficiency furnaces. Hot-surface igniters and flame sensors are the common failure points at the 10-15 year mark.
Rural Weld County properties
Propane furnaces are common outside town limits. Propane ignition needs correct orifice sizing and manifold pressure, so we bring a manometer on every rural call.

PhotoFailed igniter on a 2011 Goodman
Before: A Severance homeowner had a furnace clicking every few minutes with no heat. The igniter read open on the multimeter, and the flame sensor was coated with carbon, which explained the intermittent lockouts over the past month.
After: We replaced the igniter and cleaned the flame sensor. The furnace lit on the first cycle and held through three test runs. Flame signal read a steady 4.2 microamps, and the house was back to 70 degrees within two hours.
Control board fault in Windsor
Before: A Windsor rental had a furnace that would light, run 30 seconds, then shut off and retry. The tenant had already reset the furnace twice. The igniter tested fine, but the control board was not holding the gas valve open after flame proving.
After: We replaced the control board and verified the ignition sequence across three cycles. The short-cycling stopped completely, and the tenant stopped calling about no heat. Total repair time was about two hours on site.
Propane ignition in rural Weld County
Before: A rural property outside Severance had a propane furnace that glowed but would not light reliably. Manifold pressure was set too low, so the igniter was firing into a weak gas supply. The homeowner had already replaced the igniter once with no improvement.
After: We set manifold pressure to the manufacturer spec with a manometer and confirmed with a combustion analyzer. The furnace lit cleanly on every cycle. The homeowner avoided a second unnecessary igniter replacement.
Ignition Problems We Fix in Severance Homes
Most ignition calls fall into a handful of patterns.
Furnace clicks but never lights
The igniter is trying to fire but the burners never catch.
Furnace lights then shuts off after a few seconds
The flame lights but the control board does not see proof of flame, so it shuts the gas off.
Furnace banging noise on startup
Delayed ignition lets gas build up before it lights, which causes a small boom. It is hard on the heat exchanger and worth fixing right away.
Pilot light won't stay lit
On older standing-pilot furnaces, a weak thermocouple lets the pilot drop out and the furnace never gets to main flame.
Furnace blows cold air with no ignition attempt
The blower runs but the igniter never glows, which usually points to a control board that is not sending voltage or a failed limit switch.

What Severance Customers Say
Furnace was clicking every few minutes and never lighting. The tech metered the igniter, showed me the open reading, and had a replacement on the truck. Had heat back in about 90 minutes. He also cleaned the flame sensor while he was in there, which I appreciated.
Called on a Sunday night when the house hit 59 degrees. They walked me through what to check on the phone and had a tech out first thing Monday. Turned out to be the control board, not the igniter, and they proved it with a meter instead of just swapping parts.
We manage several rentals around Severance and Weld County. These guys handle our ignition calls and always send the old part with the invoice. That is why we keep calling.

(970) 1234567A hot-surface igniter replacement is usually on the low end; a control board or gas valve repair pushes toward the top. Diagnostic time is built into the quote, so the number you hear is the number you pay.
The three most common causes we find are a failed hot-surface igniter, a dirty or failed flame sensor, and a control board that is not sending voltage to the igniter. Less often it is a gas valve or a cracked igniter from thermal stress. A multimeter reading on the igniter tells us which one in about 20 minutes.
We do. Severance Furnace Repair Pros has handled ignition system repair Severance CO homeowners need since 2016, on gas, propane and electric furnaces from Carrier, Trane, Goodman, Rheem, Lennox, Bryant, York and American Standard. Call (970) 1234567 and we will get a tech to your address.
