Heil Furnace Repair Guide 2019

(Updated for 2019)

If you’re looking for help fixing your Heil furnace, look no further! Our comprehensive Heil furnace repair guide will explain common issues, provide troubleshooting tips, and show you how to read your model’s error codes.

Please note, the following is for informational purposes only. Any servicing you attempt is at your own risk.

Heil, At a Glance

Backed by 100 years of dependable manufacturing and superior home comfort, Heil makes it their duty to deliver HVAC products that go above and beyond your expectations. Should you experience any issues with your Heil furnace throughout its lifetime, this comprehensive guide will provide you with the tools that you need to troubleshoot common issues.

One of the most important things to remember when considering the endurability of your Heil furnace is that regular maintenance can go a long way. The simplest task is to remember to change the air filter on your furnace regularly. By doing so, you’ll be able to lengthen the life of your unit’s blower motor while also keeping the compressor coils from getting clogged.

An air filter that’s able to function properly will most certainly result in a furnace that’s able to provide its highest level of efficiency.

How to Replace Your Heil Air Filter

  1. Remove the lower panel towards the front of your Heil furnace.
  2. Locate your filter. Whether it’s an upflow or horizontal flow model, it’ll be on the side next to the air return or at the bottom of the unit.
  3. Slide out the whole filter-holding rack, and remove the end cap.
  4. Once the end cap is removed, pull out the air filter and replace it with a new one. Make sure to insert the new filter in the same direction as the previous one.
  5. Replace the end cap and then slide the holding rack back inside your Heil furnace. Put the cover back on your unit.

What’s Wrong With Your Heil Furnace?

Common Furnace Problems and Troubleshooting

Always remember to shut your Heil furnace completely off before you open it up to attempt any diagnosis or repair.

Is your furnace...The problem might be your...What's wrong?How you can fix it:
Not heating?Fuse or Circuit BreakerYour furnace’s electrical system has potentially shorted, or the power switch has blown.Reset the furnace-associated circuit breaker. If it has blown, you will have to replace it.
IgniterThe furnace’s igniter might either be cracked or defective.Check the part for cracks, replace the igniter if it’s cracked.. If it isn’t, test with a multimeter for continuity.
Cycling irregularly?ThermostatYour unit’s thermostat might be adjusting incorrectly.Should the thermostat have an adjustable calibration scale, use this to adjust the heat anticipator. If this doesn’t work or you don’t have a scale, replace the thermostat.
Not blowing hot air?Blower MotorThe blower motor might be burnt out. If this doesn’t seem to be the case, then the connecting belt may have snapped.First, see if power is reaching the motor. If it is but isn’t running, the motor has failed. If the motor runs but air doesn’t move, the connecting belt has probably broken. Replace the belt.
Blowing too much air?Control BoardIf the relay that regulates the blower motor on the control board has failed, it will continually send voltage to the motor.Replace the control board.
ThermostatThe contact that controls the blower motor on your thermostat may be sticking.Use a multimeter to check for continuity. If it appears the thermostat is the issue, replace it.
Starting and then stopping shortly after?Flame SensorYour furnace’s flame sensor detects if a flame is present. If it is either defective or dirty, it will not be able to detect a flame.If dirty, use a fine abrasive pad to clean the sensor. If faulty, replace the flame sensor.

When to Get a Technician for Heil Furnace Repairs

Should you begin to experience some issues with your Heil furnace, it’s never a bad idea to contact a trained heating and cooling technician. Although you may be able to diagnose your unit’s issue, repairing it yourself can sometimes be an unworthwhile task. Some of these issues are:

If your furnace repeatedly turns itself on and off, it’s likely that the unit is not circulating properly.
Should your Heil unit stop producing heat, begin to leak or drip, or make previously unheard noises (banging, whistling, gurgling, etc.), an internal component could potentially be broken.
