What's Included in Board Repair
Every Furnace Control Board Repair Severance CO visit includes a full diagnostic, the repair or replacement itself, and a complete system test before we leave.
Work order
Furnace Control Board Repair- Full Board Diagnostic: We test the board's inputs and outputs with a multimeter, check the transformer, thermostat signal, igniter, and flame sensor, and confirm the board is actually the failure before recommending repair. Takes 20 to 40 minutes.
- Board Repair or Replacement: Component-level repair when a relay, capacitor, or solder joint is the issue. Full board replacement with an OEM or equivalent part when the board is cracked or the processor is dead. Common boards are stocked on the truck.
- Ignition and Flame Test: After the board is in, we run a full heat cycle and verify ignition, flame proving, and blower sequencing. We check flame sensor microamps and confirm the board reads the flame correctly every cycle.
- Gas Pressure Check: We use a manometer to verify manifold gas pressure against the furnace's rating plate. A board repair on a furnace with wrong gas pressure will fail again, so we check it every time.
- Safety Verification: Limit switch response, flame rollout, and gas valve timing all get checked before we sign off. If anything else is out of spec, we flag it and give you a straight answer on what it needs.
- Old Board Handoff: You get the failed board if you want it, plus a plain-English rundown of what failed and why. No mystery, no 'we took it back to the shop' routine.

Furnace Control Board Repair Severance CO
A furnace control board is the brain of the system. Fixing it properly means testing the whole circuit, not just swapping parts. Done right, the repair holds for years.
Furnace Control Board Repair Severance CO is the diagnostic and repair service that restores the circuit board controlling your furnace's ignition, blower, and gas valve sequencing. The board is the brain of the system: it reads the thermostat, opens the gas valve, fires the igniter, watches the flame sensor, and runs the blower motor. When a relay welds shut, a capacitor leaks, or a trace burns, the furnace either won't turn on at all or short-cycles every few minutes.
In Severance, we see board failures spike every November when furnaces wake up from summer dormancy. Weld County's dry air and wide temperature swings stress solder joints, and power surges from spring storms finish the job. If you're searching for Furnace Control Board Repair near me Severance CO because your furnace is blowing cold air or clicking without firing, the board is one of the first things we test. We stock common boards for same-day control board replacement in Severance, Colorado.

How Our Board Repair Process Works
Five steps from your first call to a furnace that runs through the night. No guesswork, no parts cannon.
Tools and Methods We Use
Each method answers a different question. Together they leave very little to guess.
Verifies manifold gas pressure against the furnace's rating plate so the board's gas valve commands produce the correct burn.
Confirms the burn is clean after a board repair by reading flue gas oxygen, carbon monoxide, and temperature.
Tests pilot safety circuits and thermocouples on standing-pilot furnaces where the board and pilot circuit interact.
Lets us look inside the heat exchanger and cabinet without disassembly, checking for cracks or debris that could affect board operation.
When Board Repair Makes Sense
Furnace is 8 to 15 years old, heat exchanger and blower are healthy, but the board failed after a power surge.
We replace the board with an OEM-matched part, verify the full heat cycle, and check the rest of the system for surge…
HomesFurnace is short-cycling and two other companies have quoted a full system replacement.
We run a full board diagnostic, test the limit switch and flame sensor, and isolate the actual fault.
HomesCommercial space or rental property has a rooftop or commercial furnace with a failed control board.
We service commercial boards with heavier input counts, source the correct replacement, and schedule the work around your business hours so tenants…
BusinessesFurnace is blowing cold air and the thermostat is calling for heat, but nothing fires.
We trace the board's outputs to the gas valve and igniter, test the flame sensor, and repair or replace the board.

How Board Repair Runs in Severance
Severance sits in Weld County at about 4,800 feet, and that altitude changes how furnaces behave. Gas appliances derate with elevation, so a board that's commanding the correct gas valve timing at sea level may run slightly rich up here. We adjust for altitude on every board repair.
Downtown Severance
Older homes with a mix of standing-pilot and modern furnaces. Board failures here often trace to age and heat stress on solder joints.
Severance High School Area
Newer builds with high-efficiency Carrier and Trane furnaces. These boards have more inputs and are more sensitive to power surges.
Weld County Road 74 Corridor
Recent construction with tight, well-insulated homes. Furnaces here run shorter cycles, which can stress boards differently than older homes.

PhotoBurnt Relay on a Goodman Furnace
Before: A Severance homeowner's Goodman furnace clicked but never fired. The board's ignition relay was welded shut, and the igniter never got voltage. The house was at 58 degrees and dropping on a January night.
After: We replaced the board with an OEM Goodman part, verified ignition on the first cycle, and checked gas pressure with a manometer. The furnace was back to full heat in under 90 minutes, and the homeowner had the old board in hand.
Short-Cycling Carrier Fixed Without Replacement
Before: A Windsor homeowner was quoted a full furnace replacement by two other companies. The Carrier furnace was short-cycling every three minutes. The heat exchanger and blower were both healthy, but the board was misreading the flame sensor.
After: We repaired the board's flame sensor circuit, replaced a weak capacitor, and verified a full 15-minute heat cycle with no cutouts.
Emergency Board Swap on a Trane
Before: A rental property in Eaton lost heat on a Sunday night. The Trane furnace was completely dead: no fan, no ignition, no thermostat response. The tenant called at 9 p.m. with the house at 55 degrees.
After: We had a technician out by 10:30 p.m. with a Trane-compatible board on the truck. The swap took about 45 minutes, and we verified ignition, flame proving, and blower sequencing before leaving. Heat was restored the same night.
Board Problems We Solve in Severance
A failing control board shows up in a handful of recognizable ways.
Furnace won't turn on at all
No heat, no fan, dead thermostat response. In a Colorado winter, a dead furnace can drop your indoor temperature below 55 degrees within hours.
Furnace blowing cold air
The blower runs but no heat comes out.
Furnace short-cycling every few minutes
The furnace fires, runs briefly, and shuts off. Short-cycling stresses the heat exchanger and wears out the igniter and blower motor faster than normal use.
Furnace clicking but not firing
You hear the board clicking but the igniter never glows and the gas valve never opens.
Furnace banging noise on startup
A banging or booming sound at ignition usually means delayed ignition, which can be caused by a board that's opening the gas valve before the igniter…
Why Board Repair Beats Replacement
A failed control board doesn't mean a new furnace.
Heat Back Same Day
Most board repairs are finished in a single visit.
Fraction of Replacement Cost
A board repair or replacement runs a fraction of what a new furnace costs.
Protects Your Equipment
A failing board can send erratic voltage to the igniter, gas valve, and blower motor. Fixing it early prevents secondary damage.
Restores Safe Operation
A board that won't read the flame sensor can leave gas flowing without ignition. That's a safety issue, not a comfort issue.

What Severance Homeowners Say
Furnace died on a Sunday night in January. Called these guys and had a tech out by Monday morning. Turned out the control board had a burnt relay. They had the right Goodman board on the truck and had us back to heat in about an hour. Fair price, no upsell, and they showed me the old board.
Our Carrier furnace was short-cycling every few minutes. Two other companies told us we needed a new furnace. These guys tested the board, found a failed capacitor and a bad trace, repaired it, and the furnace has run fine for two seasons now. Saved us thousands.
I manage several rentals in the Severance and Eaton area. When a tenant calls with no heat, these are the folks I call. They diagnose the board properly instead of guessing, and their pricing is consistent. Had a Trane board swapped same day last month.

Describe what you are seeing and we will point you to the right next step.
(970) 1234567A straight board swap on a common Carrier or Goodman model sits at the lower end; a board that needs tracing and component-level repair or a rare OEM part pushes toward the top. The diagnostic fee is disclosed upfront, and you approve the repair range before we start.
The three most common causes we see in Severance are power surges from spring and summer storms, heat stress on solder joints from years of heating cycles, and moisture from condensation or a leaking humidifier. Weld County's dry air and big temperature swings also work solder and relays harder than in milder climates. A failed capacitor or shorted gas valve can take the board down with it.
