Get your Coleman EB15B producing steady heat again with genuine OEM replacement parts from Repair Clinic. The EB15B is a 15 kW electric furnace (15) in Coleman’s EB series, a Coleman Evcon line supported by Johnson Controls and common in manufactured homes. Because it heats with resistance elements, the parts that matter most are the heating elements, the sequencers, the limit switches, and the blower motor. Confirm each part on the EB15B parts list, then browse all Coleman furnace parts.
How the EB15B Electric Furnace Works
This EB15B furnace divides its 15 kW output across multiple elements that sequencers bring on in timed stages, preventing a large current surge when the thermostat calls. Each element circuit has limit protection that opens if airflow drops. With no combustion, there is no EB15B igniter, no EB15B flame sensor, no EB15B draft inducer motor, and no EB15B heat exchanger; shoppers searching those terms usually need an element, sequencer, or limit. The EB15B manual and EB15B diagram show element staging and wiring. For EB15B repair steps, use the model troubleshooting page. Shut off every breaker feeding the unit before testing.
Most Replaced Components on This Electric Furnace
Heating Elements and Partial Heat
With power off, test each element for continuity. One open element lowers output, so the air feels cool and the furnace runs longer. Replace failed elements with the same kW rating.
Sequencers and Staging
A sequencer that fails open leaves its element off; one stuck closed keeps an element on after the call ends. Check voltage on both sides of each sequencer during a heat call and match replacements to your diagram.
Limit Switches and Fuses
Repeated limit trips usually mean low airflow, so replace the filter and confirm blower speed first. A blown fuse calls for a check for shorted wiring or a grounded element. Replace the limit switch if it reads open at room temperature.
Blower Motor and Capacitor
If the blower hums or starts slowly, test the run capacitor first; a reading more than 5 to 10% below rated value causes the same symptoms as a bad motor. Replace the blower motor only when the capacitor is good.

EB15B Furnace FAQ
Why is my furnace blowing cool air?
One or more elements or sequencers have usually failed, so only part of the 15 kW output reaches the airstream. Test each with the power off.
Does this furnace have an igniter or flame sensor?
No. It is electric, so it has no igniter, flame sensor, draft inducer, or heat exchanger. Heat comes from elements staged by sequencers.
Why does the limit keep tripping?
Low airflow from a dirty filter, closed registers, or a weak blower capacitor. Fix the airflow before replacing the limit switch.
Is this a Carrier furnace?
No. It is a Coleman electric furnace. Order parts from this model’s list rather than from Carrier gas furnace listings.
